# sankey diagram python

A Sankey Diagram is a visualisation technique that allows to display flows. Several entities are represented by rectangles or text, and linked with arrow that have a width proportional to the importance of the flow. You are allowed to adjust the gap between nodes and the gap between the node and flow link for all plots together. Please use ide.geeksforgeeks.org, generate link and share the link here. Sankey diagrams are commonly used for purposes like population migration, website user journey, the flow of energy, the flow of other properties (oil, gas, etc. Sankey diagrams are a type of flow diagram in which the width of the arrows is comparative to the flow rate. As an example, you might start with 100% of a fuel’s energy on the left side of the diagram… I am impressed by the Sankey diagrams produced with ‘sankeypython’, a new open source project. The best way to get started is to use it in a Jupyter notebook (more advanced users can use it outside the notebook environment to export JSON/SVG but this is still under development; see this comment ). 1.

• please put the code inline in the question (as per the faq) Apr 17 '12 at 21:07

First of all, the best way to optimize any code is to run it through a profiler to find the bottlenecks.

Assuming you've already done that, here are a couple very minor things:

1. This code:

for(var i = 0; i < array.length; i++){

results in the length property being queried on each iteration. Obviously this won't amount to much difference if the number of iterations is small, but as a general rule I try to always cache the value:

for(var i = 0, len = array.length; i < len; i++){

And you should be caching property accesses on any objects if you use them in multiple places. For example, instead of using array[i] in several places within a loop, store it in a variable and use the variable instead.

2. I'm not sure how expensive multiplication is compared to addition in JS (and again, if array.length is a small value this won't make a difference), but instead of calculating this value every iteration:

var x = 96+(100*i);

You could just increment it within the loop:

var len = array.length;
for(var i = 0, j = 0; i < len; i++, j += 100){
var x = 96 + j;
var y = 60 + j;

• Thanks a lot for the suggestions! I ran this test for multiplication vs. addition: jsperf.com/addition-vs-multiplication, look like multiplication is faster, at least in Chrome. Apr 18 '12 at 14:46
• Nice! Very interesting... Apr 18 '12 at 15:05

I agree with seand above, I would also add:

\$(window).resize(engine.handleResize);

This might results in more resize events then you would expect, as the user resizes the window many events will be triggered causing needless updates. Coincidently I just released a helper to solve this exact problem, you can see it in action here: http://limit.gotsomething.com

Another (and this is really a preference) is rather than have various colors sprinkled through your code it might be best to declare them all in one spot. Making updating the UI much easier (especially for non developers)

Lastly, your stack for history is a nice feature, however you might consider future proofing it a bit by not only storing the colour but the attribute/method itself. This way should you introduce the ability to change stroke, opacity etc. it will be supported. Just a thought.

Regardless, neat app and the code overall is very good!

Marc.

• Thanks a lot for your suggestions. Your limit helper is pretty slick, I'm sharing it with my coworkers! Apr 18 '12 at 14:51


text:
A 'rig' R has a commutative associative addition, an associative multiplication that distributes over addition, an element 0 with r+0 = r and 0r = 0 = r0 for all r ∈ R, and an element 1 with 1r = r = r1 for all r ∈ R.

A rig is 'idempotent' if rr = r for all r ∈ R.

The free idempotent rig on two generators is finite. But how many elements does it have?

It has at most 4⁷ elements, but in fact far fewer.

(1/n)

#algebra

We can start by taking two elements a and b and multiplying them in all ways subject to associativity and the idempotent law. We get just 7 elements:

1, a, b, ab, ba, aba, bab

Then we start adding these. In an idempotent rig r + r + r + r = r + r for any element r, so we get at most 4⁷ elements.

Why is that equation true? Because

(1+1)² = 1 + 1

(2/n)

But the free idempotent rig on two generators has far fewer than 4⁷ elements! After all, it obeys many more relations, like

a + ab + ba + b = a + b

(Notice that we can't get from this to ab + ba = 0, since we can't subtract.)

So, how many elements does it have?

By the way, the free idempotent rig on 3 generators is probably infinite, since there are infinitely many 'square-free words' with 3 letters:

en.wikipedia.org/wiki/Square-f

(3/n, n = 3)

@johncarlosbaez hang on do you mean a +ab +ba+b=a+b?

@johncarlosbaez
I believe the number is small enough that it's hand-countable (the figure I've gotten is 278 though it's bashy enough I've likely made a mistake)

@alexthecamel @johncarlosbaez
Taking the last few observations into account, my current upper bound count contains at least...
Terms where at most one term of each degree appears,
$$1+3 \times 2^3 \times 3^3 + (2 \times 3) \times 2^2 \times 3^2 + (2\times 3) \times 2 \times 3 + 2 \times 3 = 907$$
That's "0", terms with non-zero deg 1 coeff, terms with non-zero deg two coeff etc.
... that's already more than @alex counted, are there identities for terms like $$1 + a + ab + aba$$ I'm missing?

@rogers @johncarlosbaez
you do have ab+ba=(ab+ba)^2=ab+ba+bab+aba=(aba+bab)^2=aba+bab, right?

@alexthecamel @johncarlosbaez that specific one wouldn't affect this count, but maybe there's a similar one for $$ab + aba$$?

@rogers @johncarlosbaez
will get a picture of the categories I have when my phone charges enough

@rogers @johncarlosbaez
hopefully it is not too unclear what I mean here

@rogers @johncarlosbaez
of course 4^7 is a small enough number that you could just computationally build a graph with vertices connected with the x+y=x+xy+yx+y eq relation and find connected components

@alexthecamel @johncarlosbaez so far we have only been using two-term relations. Many of the three-or-more term relations are already accounted for that way, but there are enough possibilities that one should probably try to prove that there are no extra reductions?

@rogers @johncarlosbaez
i think >2 term relations don't add any more constraints: eg
x+y+z=x+y+xy+yx+z=x+y+z+xy+yx+xz+zx=x+y+z+xy+yx+xz+zx+zy+yz=(x+y+z)^2

@rogers @johncarlosbaez
I guess I've not accounted for relations of the form
x(y+z)^2=x(y+z)? I don't think I'm missing any which are nontrivial but that is a bit of an oversight

@rogers @johncarlosbaez
ok i've updated my code to just brute force check + and * are well defined, so there's no problems here
if i'm doing the free rig on n variables i'd have to be more subtle I assume.

## University Calculus: Early Transcendentals (3rd Edition)

To prove the limit, prove that given $\epsilon\gt0$ there exists a $\delta\gt0$ such that for all $x$ $$0\lt|x|\lt\delta\Rightarrow|f(x)|\lt\epsilon$$
$\lim_{x\to0}f(x)=0$ if $f(x)=2x$ for $x\lt 0$ and $f(x)=x/2$ for $x\ge0$ Our job is to prove that given $\epsilon\gt0$ there exists a $\delta\gt0$ such that for all $x$ $$0\lt|x|\lt\delta\Rightarrow|f(x)|\lt\epsilon$$ 1) Solve the inequality $|f(x)|\lt\epsilon$ to find an open interval containing $x=0$ on which the inequality holds for all $x\ne0$ $$|f(x)|\lt\epsilon$$ However, since we have $2$ functions of $f(x)$, we need to divide into 2 cases: *Case 1: For $x\lt0$, $f(x)=2x$. This also means $2x\lt0$, and $|2x|=-2x$ $$|2x|\lt\epsilon$$ $$-2x\lt\epsilon$$ $$x\gt-\frac{\epsilon}{2}$$ *Case 2: For $x\ge0$, $f(x)=x/2$. This also means $x/2\ge0$, and $|x/2|=x/2$ $$|\frac{x}{2}|\lt\epsilon$$ $$\frac{x}{2}\lt\epsilon$$ $$x\lt2\epsilon$$ Combining 2 cases, the open interval on which the inequality holds is $(-\epsilon/2,2\epsilon)$. 2) Find a value of $\delta\gt0$ that places the centered interval $(-\delta,\delta)$ inside the interval $(-\epsilon/2,2\epsilon)$ Take $\delta$ to be the distance from $0$ to the nearer endpoint of $(-\epsilon/2,2\epsilon)$. In other words, $\delta=\min[0-(-\epsilon/2),2\epsilon-0]=\min[\epsilon/2,2\epsilon]$ So if $\delta$ has this or any smaller positive value, then the constraint $0\lt|x|\lt\delta$ will automatically place $x$ between $-\epsilon/2$ and $2\epsilon$ so that $|f(x)|\lt\epsilon$. That means for all $x$, $$0\lt|x|\lt\delta\Rightarrow|f(x)|\lt\epsilon$$ This completes our proof.

# Selected Papers of the 6th Conference on Algebra and Coalgebra in Computer Science (CALCO 2017)

Editors: Filippo Bonchi, Barbara König

### 1. Van Kampen Colimits and Path Uniqueness

Fibred semantics is the foundation of the model-instance pattern of software engineering. Software models can often be formalized as objects of presheaf topoi, i.e, categories of objects that can be represented as algebras as well as coalgebras, e.g., the category of directed graphs. Multimodeling requires to construct colimits of models, decomposition is given by pullback. Compositionality requires an exact interplay of these operations, i.e., diagrams must enjoy the Van Kampen property. However, checking the validity of the Van Kampen property algorithmically based on its definition is often impossible. In this paper we state a necessary and sufficient yet efficiently checkable condition for the Van Kampen property to hold in presheaf topoi. It is based on a uniqueness property of path-like structures within the defining congruence classes that make up the colimiting cocone of the models. We thus add to the statement "Being Van Kampen is a Universal Property" by Heindel and Soboci\'{n}ski the fact that the Van Kampen property reveals a presheaf-based structural uniqueness feature.

### 2. Universal Constructions for (Co)Relations: categories, monoidal categories, and props

Calculi of string diagrams are increasingly used to present the syntax and algebraic structure of various families of circuits, including signal flow graphs, electrical circuits and quantum processes. In many such approaches, the semantic interpretation for diagrams is given in terms of relations or corelations (generalised equivalence relations) of some kind. In this paper we show how semantic categories of both relations and corelations can be characterised as colimits of simpler categories. This modular perspective is important as it simplifies the task of giving a complete axiomatisation for semantic equivalence of string diagrams. Moreover, our general result unifies various theorems that are independently found in literature and are relevant for program semantics, quantum computation and control theory.
Section: Categorical models and logic

### 3. Proper Functors and Fixed Points for Finite Behaviour

The rational fixed point of a set functor is well-known to capture the behaviour of finite coalgebras. In this paper we consider functors on algebraic categories. For them the rational fixed point may no longer be fully abstract, i.e. a subcoalgebra of the final coalgebra. Inspired by \'Esik and Maletti's notion of a proper semiring, we introduce the notion of a proper functor. We show that for proper functors the rational fixed point is determined as the colimit of all coalgebras with a free finitely generated algebra as carrier and it is a subcoalgebra of the final coalgebra. Moreover, we prove that a functor is proper if and only if that colimit is a subcoalgebra of the final coalgebra. These results serve as technical tools for soundness and completeness proofs for coalgebraic regular expression calculi, e.g. for weighted automata.

### 4. Termination in Convex Sets of Distributions

Convex algebras, also called (semi)convex sets, are at the heart of modelling probabilistic systems including probabilistic automata. Abstractly, they are the Eilenberg-Moore algebras of the finitely supported distribution monad. Concretely, they have been studied for decades within algebra and convex geometry. In this paper we study the problem of extending a convex algebra by a single point. Such extensions enable the modelling of termination in probabilistic systems. We provide a full description of all possible extensions for a particular class of convex algebras: For a fixed convex subset $D$ of a vector space satisfying additional technical condition, we consider the algebra of convex subsets of $D$. This class contains the convex algebras of convex subsets of distributions, modelling (nondeterministic) probabilistic automata. We also provide a full description of all possible extensions for the class of free convex algebras, modelling fully probabilistic systems. Finally, we show that there is a unique functorial extension, the so-called black-hole extension.

### 5. A classical groupoid model for quantum networks

We give a mathematical analysis of a new type of classical computer network architecture, intended as a model of a new technology that has recently been proposed in industry. Our approach is based on groubits, generalizations of classical bits based on groupoids. This network architecture allows the direct execution of a number of protocols that are usually associated with quantum networks, including teleportation, dense coding and secure key distribution.

### 6. Automata Minimization: a Functorial Approach

In this paper we regard languages and their acceptors - such as deterministic or weighted automata, transducers, or monoids - as functors from input categories that specify the type of the languages and of the machines to categories that specify the type of outputs. Our results are as follows: A) We provide sufficient conditions on the output category so that minimization of the corresponding automata is guaranteed. B) We show how to lift adjunctions between the categories for output values to adjunctions between categories of automata. C) We show how this framework can be instantiated to unify several phenomena in automata theory, starting with determinization, minimization and syntactic algebras. We provide explanations of Choffrut's minimization algorithm for subsequential transducers and of Brzozowski's minimization algorithm in this setting.

### 7. Disjunctive bases: normal forms and model theory for modal logics

We present the concept of a disjunctive basis as a generic framework for normal forms in modal logic based on coalgebra. Disjunctive bases were defined in previous work on completeness for modal fixpoint logics, where they played a central role in the proof of a generic completeness theorem for coalgebraic mu-calculi. Believing the concept has a much wider significance, here we investigate it more thoroughly in its own right. We show that the presence of a disjunctive basis at the "one-step" level entails a number of good properties for a coalgebraic mu-calculus, in particular, a simulation theorem showing that every alternating automaton can be transformed into an equivalent nondeterministic one. Based on this, we prove a Lyndon theorem for the full fixpoint logic, its fixpoint-free fragment and its one-step fragment, and a Uniform Interpolation result, for both the full mu-calculus and its fixpoint-free fragment. We also raise the questions, when a disjunctive basis exists, and how disjunctive bases are related to Moss' coalgebraic "nabla" modalities. Nabla formulas provide disjunctive bases for many coalgebraic modal logics, but there are cases where disjunctive bases give useful normal forms even when nabla formulas fail to do so, our prime example being graded modal logic. We also show that disjunctive bases are preserved by forming sums, products and compositions of coalgebraic modal logics, providing tools for modular construction of modal logics […]
