{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This example presents a choropleth map of world countries rendered as an SVG using D3 v5. It displays each country as a red-filled path on a blue sphere, with country names shown in tooltips on hover. The visualization uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for drawing, and `d3.zoom` for panning and zooming. Data loads from TopoJSON and TSV files via the world-atlas package, with `topojson.feature` processing geographic boundaries. Hover effects change fill color to red, while the base country color is also red, with black stroke outlines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d307f5247f2146cb915938c264674ae4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
