{"version":"1.0","type":"rich","title":"GeoVisualization - Choropleth map of India","description":"This example displays a choropleth map of India, rendering its states and major places as an interactive SVG graphic. It uses a Mercator projection via `d3.geoMercator` and `d3.geoPath` to draw TopoJSON features representing state polygons and city points. State subdivisions are filled with a categorical `d3.scaleOrdinal` color scheme at reduced opacity, while labels for each state and place are positioned using `path.centroid` and the projection of coordinates. The map automatically centers and scales to fit the viewport using geographic bounds. Data comes from a remote TopoJSON file, and the code updates an earlier D3 v4 implementation to D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4efd5c84c40e4f4c9b3b33678e0bf5d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
