{"version":"1.0","type":"rich","title":"Circles on a map","description":"This map visualization displays the total confirmed COVID-19 cases per country as of May 16, 2020, using red circles sized proportionally to case counts overlaid on a world map. The geographic boundaries are drawn using `d3.geoPath` with a `geoNaturalEarth1` projection, while circle radii are scaled with `d3.scaleSqrt`. Data comes from a CSV file of country-level COVID-19 statistics, joined to the world-atlas TopoJSON, and is processed via custom `loadAndProcessData` functions. A size legend and color legend are rendered using SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7dfe6fcfeedd4dee9ee1a46d7544e634?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
