Chart drawing: GDGraph or Chart?

uwevoelker has asked for the wisdom of the Perl Monks concerning the following question:

On CPAN are two distributions for drawing charts: GD::Graph and Chart.
Chart has the disadvantage of not having POD documentation (but instead has a PDF). What else are the differences between these two modules? Which one do you use?
Do you know a comparision of these two?

Thank you.

    I've just had some good successes using SVG::TT::Graph to produce charts in SVG (I then use either batik or rsvg to convert it to a raster image for the SVG-challenged).

      Nice idea!
      But for me, this is not suitable. I would like to generate the charts from a cronjob - so the smaller the better :-)

        Well, the SVG -> PNG conversion takes a bit longer than I'd like, so currently I'm only planning to use this for charts that are generated in a batch run from a cronjob. And the PNGs aren't going to be any bigger than similar PNGs generated by any other process.

    Chart uses GD to do the drawing, as does GD::Graph. Personally, I have used GD::Graph with very good results. I even wrote Graph::Template to work with HTML::Template data structures and wrap over GD::Graph.

    Personally, I would work with Template Toolkit and the graphing plugin that comes with the main distribution. A coworker of mine got it up and running in under an hour, never having used TT before. The examples, apparently, are very helpful. :-)

    I shouldn't have to say this, but any code, unless otherwise stated, is untested

    I have been using GD::Graph for a number of years. It is reliable, GD::Chart was just released this year and still has a development version number (< 1). GD::Graph offers more graph/chart style options than chart, so I guess part of the question goes back to what kinds of charts/graphs do you want to produce?

      Hello g_White,

      GD::Chart in fact is a third module, I meant Chart (it is currently version 2.3).

      GD::Graph and Chart have the same chart types (at least the standard ones I looked at).

    For a very good commercial chart package see ChartDirector. I use it and it's fast, reliable, well documented and well supported.
