{"version":"1.0","type":"rich","title":"Circles on a Map","description":"This interactive map uses circles of varying area to represent the population of each country, with data sourced from a UN dataset. Built with D3 v5, the visualization employs a square-root scale to size the circles and a natural Earth projection to render the countries. Users can pan and zoom, and hovering over a country reveals its exact population via a tooltip. The visualization also includes both a size legend and a categorical color legend, all rendered as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba77b39c84c74eb4a7daf2ff8ef175ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
