Hi Jan Alexander, before answering your question I would like to add that I don’t work for Microsoft or get endorsed by PBI or something like that. I agree this is definitely a shortcoming in PBI, but having worked with a variety of data visiualization tools (including Dash), I find PBI extremly easy an versatile. Especially the backend part allows for a lot of custom code and manipulation. You can download the desktop version for free to give it a try yourself and compare it with other tools.
