Quickstart
You want to visualize a range of numbers right in your terminal.
$ spark 1 2 4 8
▁▂▄█
And here is a sequence of random numbers.
$ seq 64 | sort --random-sort | spark

You can set the --min=<number> or --max=<number> values for your sparkline too.
$ seq 10 20 | spark
▁▂▂▃▄▄▅▆▇▇█
$ seq 10 20 | spark --min=0

$ seq 10 20 | spark --min=0 --max=30
