{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example displays a world map rendered with SVG paths, using D3.js v5 and TopoJSON. It loads geographic country boundaries from the world-atlas dataset and projects them with a Mercator projection. The code uses `d3.geoPath` and `d3.geoMercator` to generate the map, while `topojson.feature` converts the TopoJSON data into GeoJSON features. Countries appear filled in steel blue with black, semi-transparent borders, demonstrating a minimal choropleth-style base map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e50b66e81c6466dbdecfdecf1a337a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
