Fork of COVID-19 Map (Positive Cases per 100,000 People)
This choropleth maps seven-day average COVID-19 positive cases per 100,000 people across U.S. states, with color encoded via a threshold scale using d3.scaleThreshold and schemeBlues. Hovering a state highlights it in green, while a tooltip reveals additional metrics like death toll and test counts. The visualization uses d3.geoPath with the Albers USA projection, and a VoronoiOverlay enables efficient mouse interaction. Data comes from an external CSV, with state boundaries from topojson, and React manages the component rendering.
AI-generated descriptionThe colours of the states represent the relative number of COVID-19 cases per 100,000 people during the past 7 days.
