{"version":"1.0","type":"rich","title":"Chloropleth Map","description":"This example displays a choropleth map using 160 countries colored by income group, with a legend and tooltips. It loads world geometry from TopoJSON and joins it with TSV metadata, projecting paths with `d3.geoPath` and a natural Earth projection. The ordinal color scale uses `scaleOrdinal` with `schemeSpectral`, and the legend is built as a custom D3 component. Pan and zoom are enabled via `d3.zoom`, and hovering highlights the selected country in red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/88e3e7cd523e4af191f7c059fb756b26?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
