how to make charts using GD

[Aditi Gupta]

Hello everybody,
 I have a perl code that generates a sequence of values which i want to plot
on y-axis against 1,2,3... on x-axis. I've read that GD::Graph could be used
for it. But I've never done modular programming. Also, I don't know how to
install modules from CPAN.
Are there any other easier methods for drawing charts using perl?
Please help!!
 Thanks in advance,
 Regards,
Aditi
