{"version":"1.0","type":"rich","title":"Point on a World Map","description":"This example visualizes global population distribution by plotting cities as points on a natural Earth projection world map, with point size scaled by population. The map renders land masses, graticules, and country borders from TopoJSON 50m world-atlas data using d3.geoNaturalEarth1 and d3.geoPath. City coordinates are projected from latitude/longitude, with circle radii determined by a square-root scale mapping population values to a maximum radius of 8 pixels. React manages the SVG rendering, while d3.csv loads the world cities dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/26832e668eba403bba5525df365aba5c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
