Getting Started

The package com.github.systemdir.gml.examples in the Example directory contains two small demo applications to help you get started.

To use the gml writer, ensure that your project has following maven dependencies:

<dependencies>
        <dependency>
            <groupId>com.github.systemdir.gml</groupId>
            <artifactId>GMLWriterForYed</artifactId>
            <version>2.1.0</version>
        </dependency>

        <dependency>
            <groupId>org.jgrapht</groupId>
            <artifactId>jgrapht-core</artifactId>
            <version>1.0.1</version>
        </dependency>
</dependencies>

How to import to yED

After exporting the graph to a .gml file, import it in yED by using the open dialog. After importing, the graph will most likely look broken as every node is placed on top of each other. To resolve this, go to the Layout menu in yED and select one fitting layout. Further, the Fit Node to Label in the Tools menu is useful when the labels are longer than the node's widths.
