This radial tree visualization displays the fork hierarchy of VizHub projects, with nodes positioned by angular coordinates and connected by curved paths. The example uses d3 v5’s `cluster` layout, `linkRadial` for link generation, and `stratify` to build the hierarchy from project metadata fetched via `json` from the VizHub API. The SVG rendering supports zoom and pan through the `zoom` interaction module. A commented-out section suggests an alternative image-thumbnail overlay approach.
