{"version":"1.0","type":"rich","title":"Fork of Untitled","description":"A zoomable treemap visualizes hierarchical data, with rectangles sized by a user-selected measure and color-coded by an optional metric. The chart supports interactive drilling down through levels, showing breadcrumb navigation and tooltips on hover. Built with D3 v4, the visualization uses `d3.treemap` for layout, `d3.hierarchy` and `d3.nest` for data structuring, and SVG with animated transitions for smooth zooming between levels. Hover effects highlight parent-child relationships, and the code includes customizable parameters for multiple measures and tooltip fields.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e33198c4e4f44093932bfc2cba5dea6d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
