This radial tree visualizes the hierarchical structure of the Flare dataset, showing parent-child relationships as curved links emanating from a central root. The SVG rendering uses D3 v4’s `stratify` and `tree` layouts with `linkRadial` for path generation, mapping each node to an angular and radial position. Panning and zooming interactions are enabled via D3’s `zoom` behavior. Leaf nodes appear as gray circles, while internal nodes are darker, and text labels rotate to align with the radial layout. The data originates from a CSV file containing node IDs and values.
