SVGGraph 0.07

SVGGraph is a Perl extension for creating SVG Graphs / Diagrams / Charts / Plots. SYNOPSIS use SVGGraph; my @a = (1, 2, 3, 4); my @b = (3, 4, 3.5, 6.33); print "Content-type: image/svg-xmlnn"; my $SVGGraph = new SVGGraph; print SVGGraph->CreateGraph( {title => Financial Results Q1 2002}, [@a, @b, Staplers, red] ); This module converts sets of arrays with coordinates into graphs, much like GNUplot would. It creates the graphs in the SVG (Scalable Vector Graphics) format. It has two styles, verticalbars and spline. It is designed to be light-weight. If your internet browser cannot display SVG, try downloading a plugin at adobe.com.
