{"version":"1.0","type":"rich","title":"D3 World Map","description":"This example displays a black-and-white world map using the Mercator projection, with country boundaries outlined in white. The map is rendered as an SVG using the D3.js v3 library, specifically employing `d3.geo.mercator()`, `d3.geo.path()`, and `d3.json()` to load and parse a `world-110m2.json` TopoJSON file. Country geometries are extracted from the TopoJSON topology via `topojson.object()` and drawn as SVG `path` elements. The visualization appears on a simple HTML page with a custom CSS rule defining the stroke and fill for each path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac44977698fd48c9bc466cb0909e1cf2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
