{"version":"1.0","type":"rich","title":"Firefly Map of Coronavirus Case Locations","description":"A dark world map, styled with an inverted, semi-transparent basemap, displays glowing teal points marking the locations of confirmed Coronavirus cases as of March 5, 2020. Each location is represented by a single firefly-like sprite, with equal size and intensity regardless of case count, a noted shortcoming. The visualization uses React to manage the component lifecycle, an OpenLayers map with a Stamen toner-lite base layer, and custom canvas-generated radial gradients to create the glow effect. Data is sourced from the Johns Hopkins COVID-19 time series CSV, parsed with d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9c4c6426b90455ea1e81fa3168c6bc7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
