Figure 6From: An exploration of alternative visualisations of the basic helix-loop-helix protein interaction networkForce-directed tree layout in three-dimensions. Adding an extra dimension to the tree layout separates the sub-families according to evolutionary distance and makes their interactions easier to explore. The colours have the same designations as figure 1. For clarity the tree layout (A) and interactions (B) are shown separately. The three-dimensional Kinemage file is available as an additional file.Back to article page
