{"version":"1.0","type":"rich","title":"Fork of ILINet Flu Surveillance Data","description":"This visualization displays national ILI total flu cases across weeks for each year from 2015 to 2019, allowing direct year-over-year comparison of seasonal patterns. The chart uses a line mark with year as a categorical color encoding, which applies an unordered color scale to an ordered temporal field. Built with vega-lite-api, d3, and vega-tooltip, the code aggregates ILITOTAL by year, region, and week, pulling data from a Gist containing CDC FluView Interactive surveillance data. The improper color encoding makes it difficult to discern chronological trends.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2f5c6325be44c7a9cd02e2b6bc040b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
