{"version":"1.0","type":"rich","title":"CircleMap - Sars-Covid-2019","description":"A world map uses proportional red circles to display confirmed SARS-CoV-2 cases per country, with circle size scaled by case count and a legend indicating magnitude. The visualization builds on a Natural Earth projection via `d3.geoPath`, loads CSV and TopoJSON data, and projects centroids with `d3.geoCentroid` to position circles. It employs `d3.scaleSqrt` for radius encoding, `d3.format` for tick labels, and `d3.zoom` for panning and zooming, rendering with SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d439ccd07ba5487c947dc3633e235838?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
