How to plot a chart in the terminal?

It is possible to plot raster images in terminals and terminal emulators:

import matplotlib
matplotlib.use('module://matplotlib-sixel')
from pylab import *
plt.plot(sin(arange(100) / 10))
show()

This particular example uses matplotlib-sixel, a library that uses Xterm emulating a Sixel compatible terminal and ImageTrick. Similar technology could be implemented in the Linux terminal (through the Framebuffer) or emulators (kitty or iTerm2). The FOSS community has given great solutions in the last years (like libsixel).

Another option would be using X11 forwarding or using a Sixel-based printer like lsix. But all these options would happens outside the Python shell itself.

Of course, you are probably better off running a Jupyter Notebook in the server than trying to shoehorn an image in a terminal. It is probably not worth it.
