Many biological networks are multivariate, i.e., networks with multivariate data associated with their nodes. Analyzing a network in the context of its associated data can provide insight that is difficult to discover otherwise. GraphScape provides an integrated visualization that shows both the network structure and node attributes. A landscape metaphor is used with graphs displayed on a 2D plane, while the surface height in the third dimension represents node attribute value. Several attributes can be visualized simultaneously by using multiple surfaces.

The example shows a network with two attributes, one shown as the transparent red surface, the other as the wire-framed blue surface. This provides an intuitive visual representation of node-attribute distribution in the context of network structure.
