Fork of COVID-19 Map (Positive Cases)
✓ Published0🌍 Public
This choropleth map of the United States displays the seven-day average of positive COVID-19 test cases per state, using a logarithmic color scale from `d3.scaleThreshold` with a `d3.schemeOrRd` color range. State boundaries are drawn with `d3.geoPath` and the `geoAlbersUsa` projection. The visualization includes an interactive Voronoi overlay built with `d3.Delaunay`, which triggers hover states, while a custom `colorLegend` shows the threshold values. User-provided CSV data supplies the values, which are mapped to each state’s fill color.
