{"version":"1.0","type":"rich","title":"Testing","description":"This visualization presents annual U.S. influenza-like illness (ILI) totals as multi-line curves, with each year (2015–2019) shown as a separate line over weeks of the year. The chart aggregates the CDC ILINet dataset by year, region, and week using the vega-lite-api, which wraps Vega-Lite and Vega for declarative rendering. Each line uses an unordered color scale for the year field, making it harder to discern chronological trends. The code imports data via `d3.csv` and configures axis styling through a custom Vega-Lite config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cdc72a9edd664ec684811ab9f9cd1764?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
