I expect that the plot is shown in a graphical window opened somewhere on 
screen, perhaps *under* the terminal window where you can't see it. Or 
maybe even a dialog box showing an error. Until that window or dialog is 
closed, the dispersion_plot command hasn't finished and Python will just 
wait forever.
