{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"A dark, inverted basemap displays locations with confirmed coronavirus cases as of early March 2020, each rendered as a small glowing firefly-like sprite. The visualization uses OpenLayers with a React component, drawing points from Johns Hopkins CSSE time-series data. Sprite generation employs a radial gradient with D3’s `cubehelix` color space to create the glow effect, while vector features are styled with OpenLayers `Icon` and `Style` objects on a Canvas/WebGL renderer.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ae4f0ef8d81243d197dd9ad6354afac5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
