{"version":"1.0","type":"rich","title":"Fork of ILINet Flu Surveillance Data","description":"This line chart visualizes national influenza-like illness (ILI) totals per week, with curves for 2015–2019 overlaid to compare seasonal patterns year-over-year. An ordered color encoding for the year field makes newer years appear darker, aiding readability. The visualization uses the vega-lite-api to build a markLine with an hourly time unit on the x-axis and an amount field on the y-axis, while d3.csv loads the data from the CDC FluView Interactive source. The config customizes axis colors and label styling for improved contrast.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03bb876e061a4c6f99b0ea999eb130a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
