I like small tools on the command line. Tools which do one job well. What I used any now and then is termgraph. It’s a Python library and command line programm ingesting some kind of simple data and plotting different charts in your terminal. He, I’m a self-declared UI-Luddite after all.

Example: I looked up some traffic-congestion statistics for Germany and dumped the table into a flat text file using copy & paste, removed the German-style thousands separator . and feed it to termgraph.

Not sure how you feel about it, but I like it.
