{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map uses color to encode values across world countries. D3’s `geoPath` and `geoNaturalEarth1` projection render the map from TopoJSON data, while a TSV file supplies per-country attributes. The map color-fills each country by its `scalerank` value using an ordinal color scale. A separate legend component displays the color-to-value mapping, and zooming is enabled via the `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e796d6a635eb42cd875db1d56d70f8d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
