{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"A dark map shows each location with confirmed coronavirus cases as of March 5, 2020, using a glow effect reminiscent of fireflies. The visualization plots all case locations, regardless of case count, using a shared sprite style. Built with React and OpenLayers, it loads a Stamen toner-lite basemap and creates a radial-gradient canvas sprite for each point via `generateSprite`. Data comes from the Johns Hopkins CSSE COVID-19 time-series repository, filtered to include only locations with positive counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b49bf186a0f64eea94ac6c927c64e259?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
