This visualization maps the number of certified organic food operators across French administrative departments, using a choropleth-style representation to reveal regional disparities in organic agriculture density. The data is sourced from the Agence Bio public API, which is queried via a shell script that iterates through department codes. The script uses `curl` and `jq` to extract the `nbTotal` count for each department, storing results in a semicolon-delimited text file. The final map likely employs `d3.geoPath` for rendering the department boundaries, with color intensity or a similar visual encoding driven by the fetched counts.
