{"version":"1.0","type":"rich","title":"Covid-19 Time Series: Total Number of Cases Worldwide Since 01/02/22","description":"This visualization displays the cumulative number of COVID-19 cases worldwide on a Mercator projection map, with each country represented by an orange circle whose radius scales with case count. A date slider lets users scrub through time from January 22, 2020, with circles updating via d3 transitions. Built with D3 v5, it uses d3.geoPath, d3.geoMercator, d3.scaleSqrt, and d3-zoom for interactivity. Hovering reveals tooltips with region and case totals. Data comes from Johns Hopkins via the Humanitarian Data Exchange, rendered as SVG with smooth animations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1949614f184a4868b453695960a9be23?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
