{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"This example uses a geographic map to visualize the populations of cities worldwide. The visualization shows cities as sized points on a world map. A square-root scale maps a city's population to the radius of its corresponding circle. The visualization is rendered using SVG and the React framework. The code uses d3's `geoNaturalEarth1` projection, `geoPath`, `geoGraticule`, and `scaleSqrt`. The underlying geo data comes from the World Atlas TopoJSON, and city data comes from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/595ab5ff83de4376bc8b8f643be0f557?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
