Kind of Free
But wait. Let’s clarify what we mean when we say “free and open-source.” Open-source tools are always free. Free tools are not always open-source.
Software that is free but not open-source often has a free tier. The free tier has limitations. The free version may be enough. Or you may find that you need to pay for a commercial license to get additional features.
Both Power BI and Tableau are free but not open-source. Both offer a free license with limited functionality.
