{"version":"1.0","type":"rich","title":"D3 World Map","description":"This example displays a world map rendered as black countries with white borders on an SVG canvas. It uses D3.js version 5 and the `d3.geoMercator()` projection to transform geographic coordinates, with `d3.geoPath()` drawing the country boundaries. The map data is loaded from a GeoServer WFS endpoint as GeoJSON, which is then converted to TopoJSON via the `topojson` library to structure the geometries for rendering. The visualization showcases D3’s ability to handle geographic data through its projection and path APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b35cb2066b4048f2a56c69ec8a168f22?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
