I started using Columns.ai yesterday and was already able to generate a few nice data visuals. It takes some getting used to though, so I have watched a few videos on their channel on YouTube https://www.youtube.com/@columnsai/videos . I'm still trying to figure out a few things but I think that will come with a bit of experience with the app. I would love for the owner to hold webinars from time to time, to help us learn some of the new or less obvious ways of getting the most out of the app.
