I developed fuel-prices.eu as a side project using data from the Weekly Oil Bulletin provided every week(or almost) by the European Commission. PHP and MySQL helped me with the back site work and chart.js helped me a lot with the chart and data representation of the Diesel and Euro-Super 95 data flows.
The data range is from 2015 inclusive to our present week.
I also have in plan to add to the database all of the data beginning from 2009, that means a lot of PHPmyAdmin work for me in the next future.
For more informations about this project you can contact me.
