{"version":"1.0","type":"rich","title":"Fork of world map w/ cities & countries pop!","description":"A world map visualization displays cities with populations over 50,000 as scaled circles, while country polygons are shaded by population density with hover tooltips. Using React with the d3-geo-projection library, it applies a natural Earth projection and renders graticules, geographic lines, and country boundaries via `geoPath`. City radii use a square-root scale based on population data from Simplemaps, while country opacity maps to UN population data from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f6cb0c9b009465ab16565900302ca1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
