{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays world countries using a natural Earth projection, with country boundaries rendered as interactive SVG paths. The visualization uses D3 v6 and TopoJSON to load and convert world-atlas data from unpkg, employing `d3.geoNaturalEarth1` and `d3.geoPath` for projection and path generation. Hovering over a country changes its fill from green to red, while a zoom behavior (`d3.zoom`) allows panning and scaling the entire map. The sphere background is filled blue, and country names appear as tooltips via SVG title elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c43bc5a1c1b4649a724ce921e6a354b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
