There are also many layouts that are extensions -- not predefined in the <code>go.js</code> or <code>go-debug.js</code> library,
but available as source code in one of the three extension directories, with some documentation and corresponding samples.
More information can be found in the <a href="../intro/layouts.html#CustomLayouts">GoJS Intro</a>.
