{"version":"1.0","type":"rich","title":"Untitled","description":"A multi-line chart tracks annual influenza-like illness (ILI) totals per week, with one line per year from 2015 to 2019. Each line uses a categorical color scale for the year, visually distinguishing seasons for direct comparison. The visualization is built with the vega-lite-api library, which compiles specifications to SVG via vega-lite, and it aggregates the raw CDC ILINet surveillance data by year, region, and week. The data is loaded as CSV, and the chart encodes the summed ILI totals along the y-axis against week numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c30a53ebed14bd3b210c0aad851d1af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
