Poland has been a member of the European Union for over 19 years. But sometimes, like Jason Newsted of Metallica, we're still the new members. Despite the common time measured by the age of majority, would you be able to create a regional map of my country, including the most important administrative areas? I will show you selected problems you will encounter in my native language and selected administrative data. I hope that the language diversity and the Power BI environment will allow developers and businesses from all over Europe to get to know it even better.
