{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example displays a map of Austrian districts using SVG paths generated from TopoJSON data. The code projects geographic coordinates with the Mercator projection and renders boundaries via `d3.geoPath`. It fetches the TopoJSON file from a remote GitHub repository, converts it to GeoJSON features using the `feature` function from topojson, and appends the resulting paths to an SVG. The visualization uses D3 v5, including d3-array and d3-geo modules, with a fixed viewport of 960 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38a30d9796d945f2b35ef9a7c119e376?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
