{"version":"1.0","type":"rich","title":"Mountains on a Map","description":"This visualization presents a world map where cities with populations over 50,000 are depicted as triangular mountains, with peak height encoding population size and fill color encoding country. The geographic base uses D3’s `geoNaturalEarth1` projection and `geoPath` for landmasses, graticules, and country interiors from TopoJSON world-atlas data. City data comes from Simplemaps and is rendered as SVG paths within React. The color scale is generated using D3’s `hcl` interpolation, and hover effects highlight individual mountains.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/77a2f42571494263931b8c4d38b7d63c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
