{"version":"1.0","type":"rich","title":"Fork of CodePen - D3 TreeMap","description":"A zoomable treemap visualizes the hierarchical distribution of top-grossing movies, grouped by genre, with each tile sized and colored by category. The visualization uses D3 v5’s `d3.hierarchy` and `d3.treemap` to compute the layout, while click interactions and a zoom-out button invoke transitions that re-scale the x and y domains for drill-down navigation. Movie data is loaded from a local JSON file, and tooltips display details on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4395b32242f42eaae481cbd8e6f02d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
