<h1>Style</h1>
Styling is applied in the following order:
<ol>
<li>Node default style (see wiki)</li>
<li>CSS on the page</li>
<li>Class definitions inside the graph definition</li>
<li>Inline styling inside the graph definition</li>
</ol>
and the last styling applied is the resulting styling. For instance, "Class definitions inside the graph definition" overrides styling from "CSS on the page".
