Saul Pwanson demonstrates how to quickly explore, filter, and analyze large datasets in the terminal using VisiData.

VisiData is a data exploration and manipulation multitool for terminal users. This demo takes a two-month sample of 311 complaint data from NYC and shows how VisiData can be used to quickly drill down into data, plot points on a virtual map, and select a range of points to save the source rows.

What people say. Recommended as a mind-blowing demonstration of VisiData's power for terminal-based data exploration.

Highly recommend this as well, it has been a godsend for me for digging into multi-GB Cloudfront log files and extracting stats and patterns. There is a good (albeit a bit old now, as the interface has been overhauled since) quick demo video from VD's creator : link to this video

Thanks for your comment - I wouldn't have clicked on the video link otherwise, and it was well worth it. For others who usually skip videos, here is a link which skips the intro, getting your time investment to under 4 minutes: link to this video

The "video demo" is pretty buried in the site, here it is for your enjoyment. Like most viz, seeing it in action makes it much clearer than reading about it. link to this video

Not sure about saving but, more importantly for me, it can read sqlite DBs, which has been a godsend whenever I need to take a quick glance at some random DB just to see what kind of tables it holds and what does the data look like. I know my SELECTs but I can't, for the life of me, remember what are the commands to check schemas and DB metadata on sqlite ("Was it .describe? Maybe .schema? Or perhaps \t? Gah, let's check the help once again..."), so knowing that visidata gets me there much faster feels good. > Also looks powerful in it's own right If you aren't convinced of that yet, I'd simply suggest to take a look at this lightning demo (~5 mins): link to this video

If you aren't familiar with Visidata, this video gives a pretty good idea of what it can do: link to this video It seems like making a living on shell tools can be difficult to impossible. The author Saul is using Patreon to help fund his work on this tool. I love this tool, and hope others can help support him too. Maybe this "duo-repo" approach will allow him to do this full time.

On “Revisiting the Arcan Project”

The section "TUI : Text-based User Interfaces" resonates with me strongly, and is somewhat relevant to the WTF thread1 from yesterday, in particular this subthread2 about GUI vs TUI. Compare the statements: > terminal protocols are ghastly display server protocols in disguise vs > > At what point do we just say why not 'install a modern GUI'? > I have yet to see a modern GUI that didn't put pretty little animations a higher priority than being modular and configurable and having as much or as little data density as I desire > Command lines3, on the other hand, do it natively if not intuitively. Which brings up few interesting observations: * Terminal vs graphical is almost completely o…

Why not visidata? link link to this video (It does much, much more than pretty printing, but no reason you can't use it for that.)

Probably some of the functionality showed off here, link to this video , besides the handling of large amounts of data.

Chrome debugger tools? htop? visidata 1? Clicker games are interesting in that they start bare and end up filling the screen with controls. Rerun visualizations come to mind too 2. -- 1: link to this video 2: link
