{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This fork of a choropleth map colors world countries by income group using a spectral color scale. The visualization uses D3 v5 and the `geoNaturalEarth1` projection with `geoPath` to render country shapes from the world-atlas TopoJSON and TSV data. A custom `colorLegend` displays the ordinal color scale as circles and text, and zooming is enabled through D3’s `zoom` event. Hovering a country turns it red, and tooltips show its name and additional text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6d4187e72b914bb2bbd6ee78850ae84d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
