There is a UML diagram on that page. It has three different kinds of connections. The shared aggregation connection, the generalized connection (triangle arrow), and the other one... How do I get the other one in Visio? I can't find it...
Thanks.
It isn't "there". You need to specify the "Begin" and "End" shapes for your line, from the Format -> Line menu (or "More line ends" in the lines drop-down menu)
