{"version":"1.0","type":"rich","title":"Mountains on a Map","description":"The visualization renders a world map where each city with a population over 50,000 is drawn as a small triangular \"mountain\" whose height corresponds linearly to population and whose color encodes the country. The map includes graticules, country boundaries, and a light sphere background. It uses D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule`, with React managing the SVG rendering and data loading via `useCities` from a Simplemaps CSV. Color is assigned using `scaleOrdinal` with `hcl` hues.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad8e1e57919a47f49af6d31815219327?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
