{"version":"1.0","type":"rich","title":"D3 Treemap","description":"This D3 Treemap visualizes hierarchical data by representing each leaf node as a rectangle, with size determined by the `Quantity` field and colored steelblue. It loads comma-separated data from a GitHub Gist using `d3.csv`, parses numeric columns, and applies the `d3.treemap` layout to compute tile positions. The SVG rendering appends grouped rectangles and text labels for each country, with cell dimensions derived from the layout's `x0`, `y0`, `x1`, and `y1` values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5851116db5af4388b635b55d6f12db64?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
