{"version":"1.0","type":"rich","title":"Country map with Topojson data","description":"This example shows a Mercator projection of Africa rendered as an SVG map, with each country outlined in white and filled with teal. The code loads GeoJSON data from a GitHub Gist URL using `d3.json`, then uses `d3.geoMercator` to define the projection and `d3.geoPath` to generate the SVG path data for each feature. The map is centered within a 600x400 SVG canvas, and the projection is scaled and translated accordingly. The visualization relies on D3 v4 and the `d3-geo-projection` library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8345152bd009424d8cfbe57676742929?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
