This visualization displays a subset of the DBPedia ontology as a psychedelic circle pack, with each circle representing a class and circles nested to show hierarchical relationships. The rendering uses D3.js 7.8.5 functions including `pack()`, `stratify()`, and `interpolateRainbow` to generate vibrant, animated colors based on hierarchy depth. Circles have a glowing filter effect and pulsing animations defined in CSS. The data is loaded from a Gist containing a CSV with class-subclass relationships and counts, filtered to only include classes with over 500,000 instances.
