graphics in perl

We are running perl 5.8.5 on a Linux machine that is running apache 2.2.6 with mod_perl 2.0.3. Our data is in a MySQL database (MySQL 5.0.45)

We have been asked to write a web application that requires plotting capabilities. We do most of our web programming in perl so I am looking for a perl module that has the following features:
1. ability to create histograms
2. ability to create x,y plots
3. ability to zoom in on a portion of the graph
4. ability to calculate the distance between 2 points on the graph
5. ability to hover on a point and bring up some text

Does anyone have any suggestions for which perl modules we should look into?

Thanks for any information.

I'd recommend interfacing with R (http://www.r-project.org)

Uhm, dude... a Perl module won't do that because Perl is a language,
not a display technology.

You're looking for something like Shockwave Flash. Though you can
certainly have Perl generate everything.

For drawing graphs you can have a look at google graph api
(http://code.google.com/apis/chart/)

I've once used another cart libray offering API in different languages
see : http://www.advsofteng.com/product.html

And then there is GD::Graph, but I have no experience with this.
For basic graphic functions look at Imager (imager.perl.org)

There are a lot of perl APIs built over various graphics packages.
You can start with this list:
http://search.cpan.org/modlist/Graphics

You might also try searching cpan for some specific keywords, because I
don't believe all the graphics modules are in that list. For example,
I've used Image::Magick for doing some basic image resizing and
conversion, but I don't see Image::Magick in that list.

To make your life easier, use a third-party Flash charting tool. It's
pretty and it's more interactive than a static jpg (for example).

The role of Perl in this case is simply to generate the data for the
flash application to load. Most of the time it's an XML document, so
that's something Perl does very well.

Did you try GD::Graph?

I'e used Visual Engineering's KavaChart <http://www.ve.com/kavachart/index.html/
> to do 1, 2, 3, and 5 above. It may do 4, but I haven't tried
anything like that with it. I have code for a simple System Load
application listed at <http://www.customvisuals.com/code.shtml>. Look
for System Load near the top of that page. You can also see something
pulling data from a URL at <http://www.customvisuals.com/> by viewing
the source of that page. Check the graph on the left side of the page.

GD::Graph is a good graphing tool. It can get quite low-level as well,
so you have to decide which visualiser works for you.

The advantage of GD::Graph is that it'd likely be rendered as a JPEG/
GIF, and that's something you can download and reuse in an executive
chart. But if you want something interactive (think click-through), then
Flash has that advantage.
