{"version":"1.0","type":"rich","title":"D3: GeoEarth","description":"A choropleth world map visualizes 2019 death rates from brain and central nervous system cancer by country, using an orange-to-red sequential color scale. The map is rendered with `d3.geoPath` and `d3.geoNaturalEarth1` projection, with country boundaries from World Atlas TopoJSON. React manages state for data loading via `d3.csv` and a custom hook, while hover interactions append tooltip text. A legend built with SVG rectangles shows the color scale’s domain, and the code uses `d3.scaleSequential` with `interpolateYlOrRd` for color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d25cdac453b14b41aea40924e376a1cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
