This radial tree visualization displays a hierarchical dataset of location categories, with nodes arranged in concentric circles and connected by curved links. The visualization supports panning and zooming interactions. Built with D3 v4, it uses the `d3.cluster` layout to position nodes and SVG paths to draw the radial connections. Text labels rotate dynamically based on their angular position, with font sizes scaling according to node depth. The data originates from a JSON file containing a provider-category hierarchy.
