This visualization is a small-multiples chart depicting the weekly incidence of influenza-like illness across French regions from January to December 2014, based on the `grippe.csv` dataset. Each region is represented as a separate line chart arranged in a grid, with time on the x-axis and reported cases on the y-axis. The lines reveal clear seasonal spikes and regional variation in flu activity, with Nord-Pas-de-Calais and Languedoc-Roussillon showing the highest peaks. The chart uses a shared scale for time, allowing direct comparison across regions, while the multi-line layout highlights regional differences in the timing and intensity of the seasonal epidemic. Built with D3 v4, the visualization uses a clean, minimal aesthetic with hover interactions to inspect individual regional trends.
