{"version":"1.0","type":"rich","title":"Activity 8 Country","description":"This example displays an India-focused choropleth map, extracting the country's geometry from a TopoJSON world dataset and fitting a Mercator projection to its boundaries. The visualization renders the mapped region as a single dark SVG path using D3 v5’s `d3.json`, `d3.geoMercator`, and `d3.geoPath` methods, with the TopoJSON client converting the country feature into GeoJSON. The code loads the world-atlas dataset from a CDN and draws the result on a 960×500 pixel SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/717dc0a2358940b48077165082b37191?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
