A choropleth map displays weekly influenza case counts across French regions for 2014, with a slider to navigate through time and a tooltip showing region names and values. The visualization merges CSV data with GeoJSON region boundaries using `d3.csv` and `d3.json`, and renders the map with `d3.geo.conicConformal` and `d3.geo.path`. A quantize color scale encodes case totals, while `queue()` loads the data files asynchronously before processing.
