The ordered color encoding (darker means more recent) makes it easy to distinguish the annual trends. It is built using the vega-lite-api and vega-lite, with data loaded from a CSV file via d3.csv. The aggregator sums ILITOTAL per region and week, and the plot supports tooltips for detailed data inspection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5187cccdbe54d039cedc38c156769ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
