import termplotlib as tpl
import numpy

x = numpy.linspace(0, 2 * numpy.pi, 10)
y = numpy.sin(x)

fig = tpl.figure()
fig.plot(x, y, label="data", width=50, height=15)

# I discovered termplot through https://stackoverflow.com/questions/37288421/how-to-plot-a-chart-in-the-terminal
# where Nico Schlömer points out its existence, thank you Nico.
