" summary

Demonstrates building a custom UICollectionViewLayout subclass (no external libraries) that computes item positions with trigonometry to create a circular graph layout. Covers overriding layout hooks, caching attributes for performance, adding a small delegate protocol to supply angles/values per item, and handling hit testing, cell reuse and animations so the graph lays out and updates in a plain UICollectionView.
