This example maps French regional data from a CSV file onto a geographic outline of France. It uses a conic conformal projection and a quantized color scale to shade each region according to a numeric value. The visualization loads GeoJSON topology for the region boundaries and joins it with the CSV data, filling regions with a five-step green color ramp, while regions without data appear gray. The code relies on D3 v4’s `d3.geoConformal`, `d3.geoPath`, `d3.scaleQuantize`, and CSV/JSON loading functions.
