My team is using Tableau, can we use Orange3 as an alternative?
That is no simple question! It depends, I suppose, on how you use tableau. You should start by looking through Orange’s documentation and tutorials (since it’s all free) and see whether you can replicate your existing workflows, and if the process feels natural to you.
It’s worth saying, that Orange’s main concern seems to be around batch workflows for machine learning, but Tableau’s main concern is about dynamic slicing and display of data.
