{"version":"1.0","type":"rich","title":"test geomercator","description":"This example displays a choropleth map of Mumbai's ward boundaries using a Mercator projection, with ward numbers labeled at each polygon's centroid. The map uses `d3.geoMercator` and `d3.geoPath` to render geographic data loaded from a local GeoJSON file, styling wards in grey or green depending on their `prabhag_no` property. Clicking a highlighted ward opens an external link, demonstrating basic interactivity with SVG event handlers. The visualization applies a custom scale and centering to focus on the city region.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec911fa1abbd4c7ba0488a6e87aec2c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
