This graph has four nodes and three arcs. Two of the nodes contain the string values "Ora Lassila" and "lassila@w3.org" respectively; i.e. they are the values of the name and email properties. A single arc labeled Author connects a node identified as http://www.w3.org/Home/Lassila with an unnamed node. Two arcs leave this unnamed node and are labeled respectively Name and Email and connect to the corresponding string value nodes.
The string value nodes are represented as rectangles, the other two nodes are drawn as ovals.
