{"version":"1.0","type":"rich","title":"Let's make a map with D3.js","description":"This example renders a world map using D3.js and TopoJSON, applying the natural Earth projection via `d3.geoNaturalEarth1` and drawing country boundaries with `d3.geoPath`. The SVG shows a blue sphere outline and light green countries with subtle black strokes. It loads country geometries from the world-atlas 110m TopoJSON dataset and converts them to GeoJSON using TopoJSON’s `feature` function. The code appends paths for the sphere and each country, demonstrating a straightforward choropleth-free geographic visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/96482c28b10b4e84868fdd6297b97dc0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
