* Demonstrates the construction of a graph visualization with a main and
* a satellite view. The satellite
* view is smaller, always contains the entire graph, and contains
* a lens shape that shows the boundaries of the visible part of the
* graph in the main view. Using the mouse, you can pick, translate,
* layout-scale, view-scale, rotate, shear, and region-select in either
* view. Using the mouse in either window affects only the main view
* and the lens shape in the satellite view.
