{"version":"1.0","type":"rich","title":"ILINet Flu Surveillance Data Interactive Visualization","description":"This interactive visualization explores CDC ILINet flu surveillance data through four coordinated panels: a line chart showing weekly patient visit patterns across years, a choropleth map of state-level influenza activity, a bar chart ranking the top states, and a multi-line chart tracking those top states over time. Built with React and D3 v5, the visualization uses d3.scaleOrdinal for categorical coloring, d3.geoAlbersUsa and d3.geoPath for the map projection, and d3.line with curveCardinal for smoothed trend lines. Users can filter by year and metric through dropdown menus, and hover or click to highlight selections across panels. The data is loaded as CSV and aggregated using custom React hooks with d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/90da929777a64d60a4051d6ba3940dc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
