The GraphStream library. With GraphStream you deal with graphs. Static and Dynamic. You create them from scratch, from a file or any source. You display and render them.

The newest version!

The Scala Renderer
==================

The Scala viewer is a 2D renderer for graphs. This document tries to describe the way this viewer is built and how it works.

The Scala viewer main class is `J2DGraphRenderer`. This is a standard `Renderer` in the viewer framework of GraphStream. The three main methods of a renderer are `open()`, `close()` and `render()`.
