Build a meta-chart-definition

Description

LibCharts aims to be a meta-charting library. Instead of writing own code to render charts, this library contains a super-model of the most commonly used features of all charting engines and depends on backend implementations to convert the meta-chart-definition into some real charts. This library provides a common view and common data providers for all supported charting engines and therefor allows the reporting engine to support the most suitable chart output for the given output type.

The meta-chart format should use JFreeChart as reference model and should also consider OpenOffice's charting capabilities, Dojo-Charting and JCharts.
