Fork of COVID-19 Map (Positive Cases)
This map of the United States shows the log number of positive COVID-19 cases per state, averaged over the past seven days, with darker colors indicating higher case counts. Hovering over a state highlights it in green and reveals a tooltip with additional metrics, including death toll, tests administered, and positivity rate. The visualization is built with React and D3 v6, using `d3.geoPath` with a `geoAlbersUsa` projection to render state boundaries from TopoJSON data. A threshold color scale and a custom color legend encode the case values, while a `VoronoiOverlay` component uses `d3.Delaunay` to improve hover interactivity.
AI-generated descriptionThe colours of the states represent the relative number of COVID-19 cases (log number of cases per day) during the past 7 days.
