Wgraph:Demo hidden

• The 'class' attribute is supported only for backward compatibility.
• Classes are identified by integer numbers.
• Classnames can be assigned to class numbers (on graph level) but classnames do not play any role within Wgraph.
• An edge can belong to one class only (or to none)
• If an edge class is hidden, the edge will not influence the layout
• If you want to hide more than one edge type you must repeat the 'hidden' command for each of them

---

The preferred way to hide edges, however, is the use of edge 'types' and the 'skip_edgetypes' command. It is not advisable to use 'class' and 'type' within the same graph.
