{"version":"1.0","type":"rich","title":"DBPedia Ontology Viz V1","description":"This circle pack visualization displays a subset of the DBPedia ontology hierarchy, using d3.pack and d3.stratify to compute a nested layout from SPARQL query results. It renders the taxonomy as nested circles with depth-based grayscale gradients, labels for ontology class names, and zoom interactions via d3.zoom. The dataset is loaded from a GitHub Gist CSV, and rendering is memoized through a custom computed function to optimize D3-based updates in a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d6e174feb504b7e9d3374e960ed5d94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
