{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"This map visualizes confirmed Coronavirus case locations as of March 5, 2020, with each point rendered as a glowing, firefly-like sprite of equal size and intensity, regardless of case count. Using OpenLayers for the basemap and React for component management, the code generates radial gradient sprites via Canvas `createRadialGradient` and a Gaussian falloff, styled with D3’s `cubehelix` color space. Data is loaded from the Johns Hopkins CSSEGISandData/COVID-19 time series CSV, and the inverted basemap enhances the luminous effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abd8a7f9cf6044e49ae2c84f1515be9b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
