This very configurable script allows you to plot a 3D (MNI space) visualisation of a brain graph, with edges represented by cylinders and vertices represented by spheres. To aid orientation, a cortical mesh can be added, as can convex hull outlines.
The colouring and sizing scheme is fully configurable for both edges and vertices.
