{"version":"1.0","type":"rich","title":"Circles on a Map","description":"This interactive map colors countries by economic classification using a diverging spectral color scale. Built with D3 v5, it renders a Natural Earth projection via `d3.geoPath` and loads data from the World Atlas TopoJSON and TSV files. A hover effect turns countries red, and the color legend with labeled circles is generated by a custom reusable function. Zooming is enabled through `d3.zoom`, transforming the map group on user interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/620977262be04e319804f3754cc043a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
