{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map visualizes the geographic distribution of artists by country, with each nation’s color intensity reflecting its artist count. The map renders in SVG using `d3.geoPath` and `d3-geo-projection` for world geography, while data loads asynchronously via `d3.json` from the Wasabi API’s `artist_all/77490` endpoint. A tooltip shows country-specific details, and the legend uses `d3-scale-chromatic` for color encoding. The visualization employs d3.v4 and is styled with a prominent bordered container, with hover interactions driven by mouse events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72c2b829acf9414db5bb995302f54cbc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
