I have always been a big fan of gnuplot as it allows you to create quick graphs on the fly, and supports piping data to it.
It's possible to create real-time graphs using this.
I figured I'd share some useful bash oneliners:

I think gnuplot is an example of a graphical application done right: you can script it, pipe to it, etc... the graphical and tu
i interfaces are interchangable.
I wish more graphical applications were written in a way that they can be combined with bash-kungfu.
