{"version":"1.0","type":"rich","title":"geoPath measures","description":"This visualization displays a world map with city populations and interactive country metrics. City markers are sized proportionally to population using a square-root scale, plotted with `geoPath` and `geoNaturalEarth1` projections. Country boundaries come from the World Atlas TopoJSON, with graticules and interiors rendered via D3’s geoPath. Hovering over a country reveals path area, measure, bounding box, and centroid coordinates, computed through `geoGenerator.area`, `bounds`, `centroid`, and `measure` APIs. Data is sourced from the Simplemaps World Cities Database.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9d12c0395cce43789a62c650e5a3b7de?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
