ESP32-S2 CircuitPython Getting Started

I have modified the force-multi-foci example to add a convex hull around each cluster of nodes.

I achieved this by using d3.nest() to create a new dataset of clusters containing the nodes in each cluster. Then in the tick() method I create and update the path element for each cluster in this dataset.
