{"version":"1.0","type":"rich","title":"Line Chart for ILINet Flu Surveillance Data","description":"This interactive dashboard visualizes ILINet flu surveillance data across U.S. states, combining a scatter plot, choropleth map, bar chart, and line chart. Users select a numeric attribute (e.g., ILI percentage) via a React dropdown, which updates the y-axis and point colors across years. The map uses d3.geoAlbers and topojson to render state boundaries, while the line chart employs d3.line with curveNatural to show seasonal trends. All marks render as SVG elements, with d3.scaleOrdinal for colors and d3.scaleLinear for sizes. Data originates from CDC FluView Interactive, loaded as CSV via d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27d436433379425598a8f63d2fcfc0d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
