GIS Data For A Project. I Apologize For The Banality Of My Request And For My English.

Hi all, I’m new to the community and also new to the world of data.

In a postgraduate course they assigned me an exercise on the QGIS software by representing a specific data model on a map, the goal is to make us practice and the topic is free.

Where can I get open data suitable for QGIS? I apologize for the banality of my request and for my English.
