{"version":"1.0","type":"rich","title":"Making a World Map","description":"This example shows how to construct a world map from GeoJSON and TopoJSON data using D3’s geographic projections. The visualization renders landmasses as filled green paths, with a blue sphere backdrop, graticule grid lines, and country borders outlined in light strokes. The code fetches country boundaries from the world-atlas dataset, converts TopoJSON features with `topojson.feature` and `topojson.mesh`, then projects them using `d3.geoNaturalEarth1` and `d3.geoPath`. React manages the component state and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a02fa09f9be348c68fb5e422fb518b62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
