{"version":"1.0","type":"rich","title":"D3: GeoEarth","description":"This interactive chloropleth map visualizes global deaths from brain and central nervous system cancer in 2019, using a yellow-to-red sequential color scale via `d3.scaleSequential` and `d3.interpolateYlOrRd`. A `d3.geoNaturalEarth1` projection renders country boundaries from the World Atlas TopoJSON, with each country’s fill determined by matching ISO country codes from a CSV to cancer mortality data. Users hover over a country to display its name and total deaths in a floating tooltip, while a legend shows the color scale range. The visualization uses React for state management, `d3.geoPath` for drawing, and `topojson.feature` for geographic data processing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03864d13c48a4d449eedf2f8da4addc6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
