{"version":"1.0","type":"rich","title":"Robinson","description":"The Robinson projection renders world landmasses and country boundaries as SVG paths, with a graticule and sphere outline layered beneath. The visualization uses the `d3.geo.robinson` projection from the geo.projection plugin, styled via CSS classes for land, boundary, and graticule elements. It loads world-50m TopoJSON data and converts it to GeoJSON using `topojson.feature` and `topojson.mesh`, then draws the paths with `d3.geo.path`. The map is centered and scaled to a 960×500 canvas, demonstrating the projection’s equal-area-like appearance.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-d62ccce9cc08aeb3d75989a69fad9bdb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
