Points on a Map","description":"This example displays world cities as semi-transparent points overlaid on a natural Earth projection, with the map rendered using D3’s geoNaturalEarth1 and geoPath for land, interiors, graticules, and a sphere outline. The points are positioned by projecting each city’s longitude and latitude through the same projection. Data comes from a world cities CSV and the world-atlas TopoJSON, loaded via d3.csv and d3.json, while React manages the component state and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0960415a65c04758b9bb8227487e1859?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
