# BIRT Eclipse ChartEngine
API Specification v 4.24.0-SNAPSHOT

This document is the API specification for the BIRT Chart Library

Start with the `org.eclipse.birt.chart.model.impl` package to determine what type of chart needs to be created.

The model.* packages represent the core chart model interfaces and enumeration classes generated using EMF
The model.*.impl packages represent the core chart model implementation classes generated using EMF
All other packages are dependencies and indirect references from the core model.
