Thank you for the early access invitation. I had some experience learning ipyvizzu and was glad to see the behaviour is consistent.
One problem I had was the lack of documentation with ipyvizzu. It is really hard to figure out what is meant in the documentation without actually seeing it. This problem is in part address now with Vizzu since I can configure everything visually. However, I would appreciate it also if the underlying code can be provided as well so I can use it as part of my data application. Is this something that is possible?
