{"version":"1.0","type":"rich","title":"Fork of Treemap","description":"This fork of a D3 treemap visualizes hierarchical data from a CSV file, showing the production values of countries grouped by continent as nested rectangles. Each rectangle uses color to represent its leaf node, and hovering highlights it while a title tooltip displays the country name and production value. The code uses `d3.csv`, `d3.stratify`, and `d3.treemap` to compute layout, then renders SVG rectangles and text labels with D3 v6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8fe7d25499274f76896291da7f5572e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
