Sure, but that&#x27;s like saying &quot;you can tell HTML was made by engineers&quot;. In both cases the defaults with 0 styling applied aren&#x27;t pretty. But also like HTML, Graphviz gives you the tools to customize the colors, fonts, edge and node styles and pretty much anything visual using style attributes, and just let GraphViz deal with its core competency of node layout. It takes some work up front to get a style template that you like and works for the type of display you&#x27;re going for, but once you&#x27;ve figured out a palette and the shapes you want you can apply them to any Graphviz graph.<p>It <i>would</i> be nice though if someone made a &quot;Twitter Bootstrap for Graphviz&quot; that at least starts you off with some prettier defaults. :)
