{"version":"1.0","type":"rich","title":"Tree Map with Drill down working","description":"This tree map visualizes the value of steel scrap exports from various countries, with each top-level rectangle representing a partner country and its total export value. The chart uses D3 v7’s `d3.hierarchy` and `d3.treemap` layout to render the hierarchical data as SVG rectangles. Clicking a country cell drills down to display the commodity-level breakdown for that country, using `transition` for smooth animated updates of the rectangles and labels. The data is loaded from a CSV file containing partner country, commodity description, and export values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4129c215b304eca9386fc52a848e095?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
