{"version":"1.0","type":"rich","title":"Fork of Choropleth map with D3.js!","description":"This choropleth map colors countries by income group using a categorical color scale from `scaleOrdinal` and `schemeSpectral`. The visualization loads world geometry from TopoJSON via `world-atlas` and joins it with tab-separated metadata, then renders paths with `geoPath` and a `geoNaturalEarth1` projection. The map supports zooming through `d3.zoom`, highlights countries on hover via CSS, and includes a custom color legend built with SVG circles and text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cb3783bc44e244d9882720366ce2703c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
