{"version":"1.0","type":"rich","title":"Mountains on a Map","description":"This visualization depicts a world map where each city with a population over 50,000 is represented as a small triangular \"mountain\" whose height encodes population size and whose color encodes the country. The map is rendered using React and D3’s `geoNaturalEarth1` projection with `geoPath`, including graticules and land boundaries from World Atlas TopoJSON. City data comes from Simplemaps, with tooltips displaying city name, country, and formatted population via `format`. Hovering increases stroke width on the mountain paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4faa818760e747b28ff44b93fd66e1ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
