Hi Vuzzi,
Can you give us a small example of what you'd like a graph to look like,
for, say three small sequences? That may help us to point you toward the
right graph-generating tools.
There are graph tools from the 'graphviz' project:

but I'm not sure if you mean this kind of graph. *grin* "Graph" is
another one of those overloaded words.
You might mean bar charts or line graphs instead. Perhaps you might be
able to use HTMLGen to generate nice HTML bar charts:

But it sounds like you might want something more. There's a Python
extension module the R statistics system, and since R has robust graphing,
you can take advantage of it:

Does this help?
Good luck to you!
