{"version":"1.0","type":"rich","title":"fresh block","description":"A treemap visualizes the assets of two political parties, A and B, with each party subdivided into individual members and their holdings across ground, building, and cash categories. A dropdown menu switches the treemap’s value metric between total, building, ground, and cash, using `d3.layout.treemap` with a sticky layout. Clicking a cell zooms into that branch with a smooth `transition`, and option-clicking returns to the root. The hierarchy comes from a JSON file, and the cells are colored by parent party using `d3.scale.category20c`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-a5e70f6ac6e40c1d2e26c0a4462f5fba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
