If you didn't start the sage server through a terminal, then the above
won't work.
I have a script that contains:
#!/bin/sh
kill -9 `cat $HOME/.sage/sage_notebook.sagenb/twistd.pid`

For a class I am teaching, I would like to display an image in the
plane---say a png-file--- and show how it is transformed under a
complex function f: C --> C. What is the best way to do this?
Thanks,

Hello,
I've recently been creating some diagrams of trees with sage and have
run into some difficulties getting the graphs to look decent. I have
frequently run into issues with labels of vertices overlapping. Is
