{"version":"1.0","type":"rich","title":"draw a world map","description":"This example displays a world map using the Equal Earth projection within an SVG canvas. The map shows country boundaries as light green shapes with dark blue oceans, rendered using `d3.geoEqualEarth` and `d3.geoPath`. It loads geographic data from the world-atlas TopoJSON file, converts it with `topojson.feature`, and appends each country path to the SVG. The visualization relies on D3 v5 and uses simple CSS classes to differentiate the sphere background from country landmasses.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c71751fe1184f3c996867daf57e7eb1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
