This is a map of french gas station. The color of markers depends of prices. There is one layer per fuel.
Data come from french government open data: https://www.prix-carburants.gouv.fr/rubrique/opendata/. This project uses the daily (jour) file.
Here is an example map: https://hatrix.fr/maps/opencarbumap/map.html
./download_data.sh
python3 read.py
firefox map.html
Government's database is updated everyday at 5am. Thus, data can be downloaded safely at 5:30am each day:
echo "30 5 * * * hatrix cd /path/to/dir/ && sh download_data.sh && python3 read.py" >> /etc/crontab
