{"version":"1.0","type":"rich","title":"Ordered Tree Map with Drill down working","description":"This interactive treemap visualizes steel scrap export values by partner country, with each country’s total represented as a colored rectangle. Clicking a country drills down to display its individual commodity categories as sub-rectangles, sized proportionally to their monetary values. The chart uses D3 v7’s `d3.hierarchy`, `d3.treemap`, and SVG rendering, with click-driven drill-down updates and smooth `transition()` animations on rectangle dimensions and labels. Data is loaded from a CSV file containing partnerCountry, commodityDescription, and Value fields.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c41f807ff1f4e3ab0d2612ca8caa0c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
