{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"This map shows the locations of confirmed Coronavirus cases as of March 5, 2020, with each point rendered as a glowing firefly-like sprite on a dark, inverted OpenLayers basemap. The visualization uses a React component with OpenLayers vector layers and a custom canvas-generated radial gradient sprite, styled via d3’s cubehelix color interpolation to create a soft glow effect. Data comes from the Johns Hopkins CSSE COVID-19 time series, filtered to include only locations with at least one case, and mapped using the GeoJSON format with vector tiles in Web Mercator projection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0ebd8b99c74479aac45d47ce048d8e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
