{"version":"1.0","type":"rich","title":"Making Maps - Country Map with TopOJSON Data","description":"This example displays a choropleth-style map of a country’s regions using D3.js geoMercator and geoPath projections, rendered as an SVG within a React application. The map draws region boundaries as dark strokes, fills each feature with an olive-green color, and overlays a yellow interior mesh to highlight shared borders. Data is fetched as TopoJSON from a public Gist, then converted to GeoJSON using the topojson library’s feature and mesh functions, demonstrating a complete pipeline from raw geodata to interactive map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8431f35f7e1b4c3682b8986b5e25dc80?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
