{"version":"1.0","type":"rich","title":"Mountains on a Map","description":"A world map displays cities with populations over 50,000 as triangular \"mountains,\" where each peak’s height encodes population size and its color encodes the country. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` for rendering landmasses and graticules in SVG. City data comes from Simplemaps, with country boundaries from World Atlas TopoJSON. Hovering a mountain reveals a tooltip with the city, country, and formatted population, inspired by the New York Times’ coronavirus death toll graphic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad8cfb3035c4449b9bbc6fdd0663ae2b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
