<B>Chart::PNGgraphB> is a perl5 module to create PNG output
for a graph.
Chart::PNGgraph is nothing more than a wrapper around GD::Graph, and its
use is deprecated. It only exists for backward compatibility. The
documentation for all the functionality can be found in GD::Graph.
This module should work with all versions of GD, but it has only been
tested with version 1.19 and above. Version 1.19 is the last version
that produces GIF output, and requires a conversion step. The default
distribution of Chart::PNGgraph uses Image::Magick for this. If youd
like to use something else, please replace the sub png2gif in
Chart::PNGgraph::Convert with something more to your liking.
