{"version":"1.0","type":"rich","title":"Fork of ILINet Flu Surveillance Data","description":"This line chart displays annual U.S. ILI (influenza-like illness) total cases across weeks, with one multi-segment line per year from 2015 to 2019. The visualization aggregates weekly ILITOTAL values by year and region, using an unordered color scale for the year field, which complicates comparison. It is built with vega-lite-api, which wraps D3 v5 and Vega-Lite, loading CSV data from the CDC FluView Interactive via d3.csv. The chart uses tooltips to show year values on hover, and the code sets axis styling through a custom config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/df3a6b1fcb184377bd552b0f9a86d190?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
