About spark
spark renders numeric values as block-character sparklines in a shell. Pass it a list of numbers directly or pipe values from another command, such as Git statistics or an earthquake feed, to create a compact visual summary.
It is a small shell script that can be installed on a system path and used in other scripts or a terminal prompt. The project documents installation through Homebrew on OS X.
