Please solve the programming task below using a self-contained code snippet in a markdown code block.

You are given an array points where points[i] = [xi, yi] is the coordinates of the ith point on a 2D plane. Multiple points can have the same coordinates.
You are also given an array queries where queries[j] = [xj, yj, rj] describes a circle centered at (xj, yj) with a radius of rj.
For each query queries[j], compute the number of points inside the jth circle. Points on the border of the circle are considered inside.
Return an array answer, where answer[j] is the answer to the jth query.
 
Please complete the following python code precisely:
```python
class Solution:
    def countPoints(self, points: List[List[int]], queries: List[List[int]]) -> List[int]:
```
