Grippe France 2014

Grippe France 2014

A choropleth map of France displays the annual sum of flu-related medical visits in 2014 across 22 metropolitan regions, using color to indicate case totals. The visualization merges CSV data with GeoJSON regional boundaries, encodes the aggregated year sum into region fill colors, and displays the exact value as text on mouseover. It is built with d3.v4, using `d3.geoConicConformal` with a centered projection, `d3.geoPath` for rendering the map, `d3.scaleLinear` for color mapping (from red to blue over a 0–4500 range), and `d3.mouse` to position the hovered label.

Carte Grippe France

This choropleth map visualizes the total number of flu cases across French administrative regions for 2014, using a blue-to-red linear color scale to indicate intensity. Hovering over a region reveals its name and total case count via a tooltip. Built with D3 v4, the map uses `d3.geoConicConformal` for the projection and `d3.geoPath` to render region boundaries from a GeoJSON file, while the data comes from a CSV sourced from a gist.
