{"version":"1.0","type":"rich","title":"Fork of world map w/ cities & countries pop!","description":"A global map visualizes cities and countries by population using a natural Earth projection. City markers sized with a square-root scale encode population, while country fill opacity encodes population data, with a distinct class for missing values. The visualization uses `d3.geoPath`, `d3.geoNaturalEarth1`, and `d3.geoGraticule` for map rendering, with data loading via `d3.csv` and `d3.json`, and React for the interface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a5c34a56fe7c45ceaeca8a7c47bc65b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
