Politicians from around the world are using Twitter accounts for direct communication with the public.…
The eruption of Eyjafjallajokull in Iceland has created disruption of air traffic around the world and particularly through Northern Europe. A similar eruption of tweets has followed, focused around a series of hastags including “#ashtag”, “#ashcloud”, and “#volcano”.
The #ashtag network is highlighted by well known technology bloggers.
In contrast the map for the tag “#ashcloud” is dominated by the UK and Scottish travel and Foreign office twitter accounts.
This image features a minor but useful tip for building multi-line tooltips. This can help pack a lot of information about a Node into the tooltip. To build a multi-line tooltip use the “&CHAR(10)&” feature to glue other columns of data together along with labels.
Add a column to the Vertices worksheet and paste something like this into it:
=”Twitter user: “&Vertices[[#This Row],[Vertex]]&” – Followers:”&Vertices[[#This Row],[Followers]]&CHAR(10)&”Description: “&Vertices[[#This Row],[Description]]&CHAR(10)&”Last tweet: “&Vertices[[#This Row],[Tweet]]
Which creates a tooltip with multiple lines containing the Twitter User name, the number of their followers, a new line containing their user description followed by their last tweet on another line. Any concatenation of columns contents can be assembled in this way.
