{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"This firefly map displays the geographic locations of reported coronavirus cases as of March 5, 2020, using a dark background with glowing teal points that shimmer like fireflies. Each location is represented by a single point, regardless of case count, highlighting the global spread of the virus. The visualization uses OpenLayers for map rendering with a Stamen toner-lite basemap, styled with an inverted CSS filter. Point sprites are generated via Canvas radial gradients using d3-cubehelix color manipulation, and the React component manages map lifecycle through hooks. Data is loaded from the Johns Hopkins COVID-19 time series CSV using d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7337f475daf6407c980884b7e3ca3079?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
