{"version":"1.0","type":"rich","title":"ILINet Flu Surveillance Data","description":"This line chart shows the annual total ILI flu cases in the US by week, with separate curves for each year from 2015 to 2019. The visualization aggregates the data by year, region, and week, then encodes year as an unordered color scale. It uses the vega-lite-api to construct the chart and d3.csv for data loading from the CDC FluView Interactive dataset. The tooltip displays the selected year, and the chart is rendered with a custom configuration for axis styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1886a53da7334d4085180c921eed5cb2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
