{"version":"1.0","type":"rich","title":"Fork of Mountains on a Map-1","description":"This visualization displays a world map with cities over 50,000 population as triangular “mountains.” The height of each mountain encodes the city’s population, while its color distinguishes the country. The map includes graticules and country borders, with a dark sphere background.\n\nBuilt with React and D3 v5, it uses `geoNaturalEarth1` for projection, `geoPath` for land and graticules, and `geoGraticule` for the grid. City data comes from Simplemaps, processed via `d3.csv`, while country boundaries originate from the World Atlas TopoJSON. Colors are generated using `scaleOrdinal` and `hcl`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d941baf9e0a4fceb82b2f7b09136810?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
