{"version":"1.0","type":"rich","title":"Fork of D3 v5 Circle-Packing","description":"This interactive circle-packing visualization displays the hierarchical structure of Fudan University’s graduate programs, organized by school and research direction. The D3 v5 code uses `d3.stratify` to convert CSV data into a hierarchy, `d3.pack` for circle layout, and a sequential magma color scale to indicate depth. Hovering highlights ancestor nodes, while leaf circles include clipped text labels. Rendering is done via SVG, with data loaded from `flare.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e17c30c004f84ffab9d0de7ab18bfc2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
