{"version":"1.0","type":"rich","title":"Fork of Circles on a map","description":"This example displays the total COVID-19 cases per country as of August 30, 2020, using circles sized by a d3.scaleSqrt on a world map. The map is rendered with d3.geoPath and a geoNaturalEarth1 projection, while country boundaries come from TopoJSON world-atlas data. Hovering highlights countries, and a size legend with a color legend—built via custom legend components—explains the scaling. The visualization supports zooming and panning through d3.zoom, with SVG circles positioned using d3.geoCentroid and the projection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d53050a210fc40fda04d183101b3298a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
