This radial hierarchy visualization displays the dependency structure of the Flare visualization toolkit, with the dataset read from a JSON file containing module names, sizes, and import relationships. The visualization uses D3’s cluster layout combined with a bundle layout to draw curved edges that connect dependent modules in a circular arrangement.
Upon mouseover, incoming links (dependants) are highlighted in brown and outgoing links (dependencies) in red, with associated nodes emphasized through font weight. The static view shows all links in blue with low opacity, and the color highlighting clarifies the directional relationships. The nodes are arranged around the circle, with labels placed outside the circumference and rotated for readability. The SVG rendering uses a radial layout with bundled edges to reduce visual clutter in the dense dependency graph of the PHP language ecosystem. The visualization is part of a gallery of data visualization examples, providing an interactive way to explore the dependency structure of the Flare visualization toolkit.
