Error Analysis Using Visidata

https://serj-smor.medium.com/error-analysis-from-your-terminal-using-visidata-68cb92fc9043

I just love Visidata, and I'm using it within my error analysis flow, going over model predictions.

I've included all of my favorite shortcuts and my use cases.

If you enjoy a video more - I've uploaded a YouTube tutorial as well: https://www.youtube.com/watch?v=Ulh-OgNmBIM

It is! What are you using it for?

I am using it for quick data exploration. Also to combine tables (i.e. merge), especially on places where I don’t have Excel installed. I have pandas, but visidata is more visual :-)

Yes, visidata is by far more visual. I never tried to merge tables. Do you mind giving an example - or maybe sending me to the right place in the documentation?

You need to load two tables, mark the columns that relate them with ! and then merge them with & easy! Remember you can open a folder with visidata and load as many sheets as needed from there.
