In fact, I've been liking it so much that I wrote a tutorial for first-time users: https://jsvine.github.io/intro-to-visidata/
(Feedback very much welcome / appreciated.)
The lightning talk is a really great sales pitch, but it's unclear how to actually replicate it. Another video of his, a recommended one after the lightning talk, again loses me a little and goes very fast. I could pause and try to understand... but it's not just about how to do it, but also about knowing that I should be looking to do certain things in the first place.
Your tutorial both gives a nice overview of what features exist, and explains very clearly how to do things. Thanks for taking the time!
Some hand-holding and guiding is very welcome... so thanks!
Thats all I needed to hear.
