+<h3>Connections between tutorial programs</h3>
+
+The following graph shows the connections between tutorial programs and
+how they build on each other.
+Click on any of the boxes to go to one of the programs. If you hover
+your mouse pointer over a box, a brief description of the program
+should appear.

+In the graph above, green octagons indicate programs that show basic
+techniques. Orange boxes indicate advanced techniques, while the programs
+shown as yellow, light blue, and dark blue boxes are applications in fluid
+dynamics, solid mechanics, and time dependent problems, respectively.
