Virus chloropleth
This visualization presents a choropleth map of the United States, displaying the total number of West Nile virus cases per state for 2015. Each state's fill color corresponds to the case count, with a logarithmic color scale ranging from white to green. Hovering over a state reveals a tooltip showing the state's name and its specific case total. The map is rendered using D3 v3 with an Albers USA projection (`d3.geo.albersUsa`), geographic paths from GeoJSON, and is styled with CSS.
AI-generated descriptionA D3 map of West Nile virus and Zika virus infections in the United States. The map is being used by GEAR UP Virginia (http://www.schev.edu/index/students-and-parents/resources/gear-up) at James Madison University as part of the "Bugs to Barcodes" project. This was built by modifying Michelle Chandra’s Basic US State Map - D3, which was built by modifying choropleth example code by Scott Murray, tooltip example code by Malcolm Maclean, and legend code example by Mike Bostock.
