COVID-19 Map (Positive Cases)
This interactive map of the United States visualizes COVID-19 positive cases by state, with fill colors encoding the log-transformed seven-day average of positive tests, ranging from 5 to 11 on a threshold color scale. A voronoi overlay, built with `d3.Delaunay.from` and `voronoi.renderCell`, enables hover interactions, while each state path (rendered with `d3.geoPath` and `geoAlbersUsa`) displays a tooltip with additional metrics including death toll, tests, and positivity rate. The visualization also includes a threshold color legend and uses React for managing the overlay component.
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.
