Python termplotlib
From wikinotes
A very useful python library that aims to reproduce matplotlib using ascii
so that it can be used on headless servers.
Unfortunately, it seems you cannot render multiple lines on one graph.
import termplotlib
fig = termplotlib.figure()
fig.plot([0, 1, 2], [1, 2, 3]) # line/chart-1
fig.plot([0, 1, 2], [1, 5, 10]) # line/chart-2
fig.show() # prints to stdout
