+Often in WeBWorK, the graphs are displayed as small thumbnail images.
+These can be difficult to read, so in these cases, WeBWorK provides
+you with a link to a larger copy of the graph. You can click on the
+small version of the image to get the larger one. For example, click
+on the diagram below to enlarge it. It will be displayed in a
+separate window; close that window when you are done looking at the
+larger graph.
