DESCRIPTION

Terminal::QuickCharts provides a small library of simple text-output charts, suitable for sprucing up command-line reporting and quick analysis tools. The emphasis here is more on whipuptitude, and less on manipulexity.

This is a very early release; expect further iteration on the APIs, and if time permits, bug fixes and additional chart types.
