=head1 NAME
CGI::Application::Plugin::DBIProfile::Graph::SVGTT - SVT::TT::Graph::Bar Graph output for CAP:DBIProfile.
=head1 SYNOPSIS
# in httpd.conf
SetVar CAP_DBIPROFILE_GRAPHMODULE CGI::Application::Plugin::DBIProfile::Graph::SVGTT
PerlSetVar CAP_DBIPROFILE_GRAPHMODULE CGI::Application::Plugin::DBIProfile::Graph::SVGTT
# in your CGI::Application subclass (needed to install callback)
use CGI::Application;
use CGI::Application::Plugin::DBIProfile::Graph::SVGTT;
=head1 DESCRIPTION
This module provides a SVG::TT::Graph::Bars graphing option for CAP:DBIProfile.
This also provides an example of non-inline graphs for DBIProfile.
The following settings control the output:
=over
=item $CGI::Application::Plugin::DBIProfile::Graph::SVGTT::WIDTH
Width of output image.
=item $CGI::Application::Plugin::DBIProfile::Graph::SVGTT::HEIGHT
Height of output image.
