{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example visualizes the geographic distribution of cities as small, semi-transparent points overlaid on a world map. The map is rendered using React and D3, with landmasses and graticules drawn via `d3.geoPath` and `d3.geoGraticule` from a Natural Earth TopoJSON source. City coordinates are loaded from a CSV file and projected using `d3.geoNaturalEarth1`, with each point plotted as an SVG circle. The styling uses a light gray for land and graticules, contrasting with the teal city points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35fdf24d229c41fba94b8d7aad291f67?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
