examples

scheme@(guile-user)> (spark '(2 5 5.5 6 10))
$1 = (▂ ▄ ▅ ▅ █)
scheme@(guile-user)> (spark '(1 2 3 4 100 5 10 20 50 300))
$2 = (▁ ▁ ▁ ▁ ▃ ▁ ▁ ▁ ▂ █)
scheme@(guile-user)> (spark '(100 275 400 300))
$3 = (▂ ▆ █ ▆)

formula

the formula for calculating the bars is as follows:

current number        index
-------------- = --------------
maximum number   length of list
