{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This example visualizes cities with populations over 50,000 as semi-transparent circles on a natural Earth projection, using a graticule, land masses, and interiors to provide geographic context. The map is rendered in SVG via React, with D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` handling projections and paths. City coordinates are projected from latitudes and longitudes loaded from a CSV, while country boundaries come from the World Atlas TopoJSON source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/18272d73d8bf4f19821042aceadfaeb5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
