{"version":"1.0","type":"rich","title":"Covid-19","description":"This visualization displays the global spread of Covid-19 cases from January 22 to March 30, 2020, using a world map. It plots reported cases as orange circles, with each circle’s radius scaled by the square-root of the case count for a selected date. The map is rendered as an SVG using D3 v5’s `geoPath` and `geoMercator` projections, while case data is loaded from a local CSV file. A slider input allows interactive date selection, though the displayed date label is currently static. Data is sourced from Humanitarian Data Exchange.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d7a9bee028845babbe678ab078ecfb8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
