 Provenance assertions can be <em>illustrated</em> graphically. The illustration is not intended to represent all the details of the model, but it is intended to show the essence of a set of provenance assertions.  Therefore, it cannot be seen as an alternate notation for expressing provenance.</p>
 
-<p>The graphical illustration takes the form of a graph. Entities, activities and agents are represented as nodes, with oval, rectangular, and half-hexagonal shapes, respectively.  Usage, Generation, Derivation, Complementarity are represented as directed edges.</p>
-
-<p>Entities are layed out according to the ordering of their generation event.  We endeavor to show time progressing from left to right (or from top to bottom).  This means that edges for Use, Generation and Derivation typically point from right to left (or from bottom to top).</p>
