This animated choropleth map shows the spread of influenza-like illness across French regions throughout 2014. Built with D3 v4, it uses a sequential color scale to encode weekly incidence rates per 100,000 inhabitants, with darker shades indicating higher values. The animation steps through each epidemiological week, updating region colors in real time to reveal seasonal outbreak patterns and regional variations across the year. Hovering over a region displays its exact count and region name, while a timeline scrubber allows viewers to navigate the data. The design uses a clean, muted palette for the map base, with the incidences highlighted by a blue-to-red diverging scheme that emphasizes epidemic peaks during winter months. The visualization is part of a course exercise (TP4) by HectorDt and is released under the MIT license.
