{"version":"1.0","type":"rich","title":"DBPedia Ontology Viz","description":"This visualization displays a hierarchical subset of the DBPedia ontology, a taxonomy of classes categorizing Wikipedia articles, as a circle packing diagram. Circles are nested to show class relationships, with color based on depth and gradients creating a 3D sphere effect. Users can pan, zoom, and click any circle to open a SPARQL query listing related Wikipedia articles. The code uses d3.js functions like `stratify`, `pack`, and `zoom` to compute the layout and interactions, with data loaded from a provided CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0e4778c184f48a4b46df14e0516dd43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
