This visualization shows the financial ecosystem of the U.S. prison system, mapping how government entities connect to private companies across sectors like healthcare, telecommunications, and construction. A circular dendrogram layout positions 76 nodes around the perimeter, with bundled radial links tracing relationships between entities. The code uses `d3.cluster` and `d3.radialLine` with `curveBundle` to draw the hierarchical connections. Hovering over a node highlights its direct connections in red and green, emphasizing source and target relationships. The data comes from a local `prisons.json` file containing nodes and links between government agencies and private corporations.
