Data visualization developed with Power Bi about historical data of the Spanish PGE estimations for different years.
Originally the data is based in the PDFs documents, wich are a little bit confusing, but wich have been converted into csv format thanks to the team of https://www.dondevanmisimpuestos.es who worked on a ruby application that ingest PDFs and generate the data in csv format.
You can find the original ruby project and the csv files in the following Github repository https://github.com/civio/scraper-pge/
You can check the live Power BI data visualization and my findings in the following link HERE .
