Customizing the Graph

To fully understand this chapter it is important that you are familiar with the graph implementation of yFiles for HTML as introduced in the graph model chapter.

In this chapter we describe several customizations of the graph and its elements. It contains stand-alone sections that do not depend on each other. We recommend that you just read the parts that are currently interesting to you, and come back later if you need more information.

You should not implement the IGraph interface or any of the IModelItems. Instead, we recommend to use the customization options described in this chapter.

This chapter contains the following sections.
