{"version":"1.0","type":"rich","title":"Coronavirus Firefly","description":"A dark map rendered with the OpenLayers library and React shows the global spread of confirmed COVID-19 cases as of March 5, 2020. Each case location appears as a glowing, firefly-like sprite generated with Canvas and a radial gradient, styled with d3’s cubehelix color space. The basemap is inverted and dimmed to emphasize the points. Data is loaded from a Johns Hopkins CSSE CSV via d3.csv, and each point is rendered at uniform size and intensity regardless of case count.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2677869bc4934425a90f9657babecb79?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
