Brief description: Polish Supreme Audit Office (Najwyższa Izba Kontroli) announced that it will investigate Polish gym & fitness market, suspecting that there might be a cartel-like agreement between few fitness businesses. We took a look at the data about business connections within these companies in National Court Register (Krajowy Rejestr Sądowy) via API developed by Moje Państwo Foundation. The data were then processed in Networkx library, resulting in projected graphs showing connections between companies that have at least one common board member or other official enlisted in NCR. We also scraped localizations of gyms and put them onto maps of Polish cities to see how companies divided the market.

Data source: Moje Państwo Foundation (https://mojepanstwo.pl/krs), websites of fitness companies

Technological stack: Python, Networkx, Pandas, SQL
