{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"This map shows the global distribution of confirmed Coronavirus cases as of early March 2020, with each location rendered as a glowing firefly-like sprite. The visualization uses OpenLayers with a Stamen toner-lite basemap, and React manages the map lifecycle. Case locations are styled using a custom canvas-generated radial gradient sprite, created with d3’s cubehelix color functions to simulate a soft glow. Data comes from the Johns Hopkins CSSE COVID-19 time series, loaded via d3.csv. The map updates over time by cycling through the dataset’s date columns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/26198b23286f442bbc0c4131c6de1b2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
