{"version":"1.0","type":"rich","title":"Covid-19","description":"The visualization maps COVID-19 case counts per country on a world map using SVG circles, with circle radius scaled proportionally to the number of cases on March 25, 2020. It displays data from the Humanitarian Data Exchange, sourced from a CSV file containing daily case numbers since January 22, 2020. The map uses D3 v5’s `geoMercator` projection, `geoPath` to draw country boundaries, and `scaleSqrt` for radius scaling. A range slider is present, though the displayed date label shows placeholder text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d20c697e803b4277a4f09d6e0690ab2e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
