{"version":"1.0","type":"rich","title":"Treemap - Global Data","description":"This interactive treemap visualizes global metrics—such as CO₂ emissions, population, and GDP—for countries grouped by region, with a dropdown to switch between twelve data dimensions. Built with D3.js, it uses `d3.treemap` and `d3.hierarchy` to compute the layout and `scaleSequential` with `interpolateWarm` for color encoding. Hovering reveals a tooltip with region, country, and metric-specific values. The viz renders as SVG, sourcing data from a bundled global dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b96b0c91d3b9426f94acd3cdc149e7d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
