It's absolutely possible. I did just do a quick search for a skill tree UI on Google which i couldnt find anything for Bakin, which is surprising. I coulda swore I seen someone somewhere had made one.
The option you have if there's no SKill Tree UI Scxript available is to make one manually, it'd be a lot of work to set up. I'd suggest you join the official Discord and ask there for better in depth help, if someone's willing to help there with your question.

Funny thing, the Glowing Icon pack DLC shows an exemple of a skill tree:

The method showed is map based, it is probably easier to do this way than going into scripting if you are new to the software

thank you for your quick responses

phantom: it was precisely by seeing this video that I wanted to create a skills tree. too bad the devs don't include the skill tree with this dlc.
