{"version":"1.0","type":"rich","title":"ILINet Flu Surveillance Data","description":"This chart displays annual influenza-like illness (ILI) total cases by week, comparing yearly curves from 2015 to 2019 using data from CDC FluView Interactive. Each line represents a year, encoded with an unordered color scale that complicates temporal reading. The visualization aggregates the original region-level CSV data with a Vega-Lite API pipeline, applying `vl.sum` and `groupby` transforms, then renders lines via `vl.markLine`. It uses vega-lite-api with vega and vega-tooltip for interactive hover details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/79fd5a3d32d545da9c6628237f0c143f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
