You sort of can and there are tools for wrapping it all up in an
installable package. More commonly you create a desktop application
using the GUI toolkit of your choice and generate the graphical output
and display it yourself (using pyplot etc)

Or....

More or less although the Django framework may well host the
server code too.

Django is a web framework so it generates web pages(HTML) as output.
Thus if you can generate png files in your python code Django can put
links to those files in its HTML output and the users browser will
display them.

Nowadays its usually via the web. Depending on how fancy you want to
get. It could simply be a static graphics file (png/pdf/jpeg etc) or
maybe a Flash graphic(not common now) or even a movie generated by
back end code. Or it could be something more dynamic controlled by
Javascript in the browser in which case your backend code simply serves
up raw data and the Javascript code turns it into dynamic graphics
within the browser screen, possibly via SVG or similar technology.

There have never been so many options for delivering content to
end users!
