{"version":"1.0","type":"rich","title":"Point on a map","description":"This example displays a natural Earth projection of the world map, with landmasses rendered in light blue and graticules in a darker blue, upon which cities are plotted as semi-transparent green circles sized by population using a square-root scale. The map is drawn with D3’s `geoPath`, `geoNaturalEarth1`, and `geoGraticule` projections, while city data is loaded from a CSV file and world topology from a JSON atlas. React manages the SVG rendering, updating the visualization once both datasets are fetched.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edab9d65841b43c0a55567ad0498ee34?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
