Wgraph:Demo hidden

• The 'class' attribute is supported only for backward compatibility.
• classes are identified by integer numbers
• 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.
