Having worked with several BI software and tools for couple years ago, and mostly with Power BI from my recent job, I have seen data visualization technologies growing incredibly fast, and to my knowledge, Power BI and Tableau are the first and second most popular business intelligence tool on the market. To be honest, I haven't even tried Tableau either for my work or study, but now I finally took some time to try my hands on with this software, and it's actually two weeks creating a dashboard from scratch.
