It's a little hard to tell without knowing more about your
user input (command language?) syntax that is translated to
or feeds the process that "autogenerates python code".

E.g., is it a limited python subset that you are accepting as input,
or a command language that you might implement using the cmd module, or ?
There are lots of easy things you could do without generating and exec-ing
python code per se. How complex is a user session state? What modifies it?
What actions are possible? History? Undo? Is the data a static passive
resource to view, or partly generated or made accessible by prior actions
in a session? Single user or collaborative? Shared access to everything or
only to static data? Etc., etc.

Some examples of user input and corresponding generated python might help,
with some idea of the kind of visualization aspects being controlled ;-)
