Super-Simple Bash Graphs

The sparkr gem is installed by default in macOS. To use it to produce simple graphs, simply run it followed by a series of integers:

sparkr 12 110 250 110 12

The result would be as follows:

This is useful for a quick and dirty visualization in scripts. For example, a series of 5, 10, 200 numbers that don’t have that much range where you’re just looking for a simple pattern. Like number of lines in logs, etc. Obviously, you can pay a lot of money for graphing frameworks and very fancy-schmancy tools. This is really just for me in small scripts. 

Note: sparkr isn’t installed on all Mac systems. to install it manually use:

sudo gem install sparkr

Thanks to Armin Briegel for pointing out that sparkr isn’t installed by default on the latest OSen.
