ILINet Flu Surveillance Data Interactive Visualization
This interactive visualization explores ILINet flu surveillance data, showing patterns in influenza-like illness percentages, patient counts, and provider metrics. It presents a multi-view dashboard including a scatter plot of states by week with size and color encoding, a choropleth map using d3.geoPath and topojson, a horizontal bar chart ranking states, and a line chart with brushed curves. Users can select different metrics and fields via dropdowns, and interact with marks through hover and click to highlight selections. The visualization uses d3.scaleLinear, d3.scaleOrdinal, and d3.geoAlbersUsa, rendering with React and SVG.
