{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors world countries according to their economic group, using a sequential spectral color scale with a clickable legend. Built with D3 v5, it loads TopoJSON world-atlas data and renders geographic paths via `d3.geoPath` with a natural Earth projection. The map supports zooming through `d3.zoom`, and hover states highlight individual countries. The ordinal color scale maps economy classifications to colors, with the legend generated by a custom reusable component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f93bad756bc416cac7c2487300b4a62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
