[TriLUG] Web App with Bar Graph - What to Use?

[Scott Chilcote]

Hi Folks,

I'd like to rewrite a web application I have that has a user entry form 
and generates some bar graphs.

I used Perl and gnuplot to do this the first time.  Managing it was a 
chore because the jpeg images that gnuplot generated had to be stored on 
the server.  The program had to keep them available and delete them 
periodically.

I had a few requests to share the app, but these requirements made it 
hard to provide it to someone else.

One option I'm considering is the GD::Graph module for Perl.  It looks 
like it would do what I need, and wouldn't require managed image files. 
It would require that GD::Graph is available on the webserver though.

I'm not opposed to using something else like JavaScript or Python 
instead.  I want to minimize setup and administration.  The application 
may wind up on a club webserver operated by hobbyists.

Any recommendations?

Thanks,

Scott C.
