This visualization shows the weekly incidence of influenza-like illness across French regions in 2014, with each region displayed as a small-multiple line chart. The x-axis represents 52 weeks from January to December, and the y-axis shows the count of reported cases per region. The chart uses color-coded lines or areas to distinguish regions, with the overall seasonal trend clearly visible: cases rise sharply in the winter months (peaking in February), decline to a summer trough, and rise again toward the end of the year. A column labeled somme2014 provides the annual total per region, allowing comparison of regional severity.
