This radial visualization displays the dependency structure of the Flare visualization toolkit, using a bundle layout to group curved links between related code modules. The code loads hierarchical JSON data and applies `d3.layout.cluster` with `d3.layout.bundle` to position nodes around a circular layout, while `d3.svg.line.radial` with bundle interpolation draws the connecting paths. Leaf nodes are labeled with class names, rotated to orient text along the circle's edge. The example builds the visualization incrementally in a React component using a `VizContainer` wrapper that implements the margin convention.
