{"version":"1.0","type":"rich","title":"Basic D3 map (Mercator) d3v4","description":"This visualization displays a basic world map using the Mercator projection, rendered as a single SVG path. The code loads GeoJSON data from an external URL and projects it with `d3.geoMercator()` and `d3.geoPath()`, scaling the projection to fit a 960 by 500 pixel viewport. The map fills the entire screen, with the SVG element sized to the full window. Built with D3 v4, it demonstrates the minimal setup required to draw geographic features from GeoJSON data using the library’s standard geo-path API.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-9c82aad9f4bc844a1358258deedd91d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
