{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map of Venezuelan parishes colors regions by population density using a red-purple sequential scale. Hovering a parish reveals a tooltip with its name and population count. The visualization uses D3 v5 with `d3.geoNaturalEarth1` projection, `d3.geoPath` for rendering TopoJSON geometry, and a threshold scale for color encoding. Parish data merges external CSV values with the TopoJSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/349e4805a9924f338e3e2539a05ec947?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
