The use of this kwarg should be properly documented. In this case, one edge will have 5mm dashes and the next will have 2mm dashes

No, all edges will have the same style, that is alternating 5mm solid line and 2mm blank line.

# vary edge styles
using Compose
gplot(g, EDGELINEWIDTH=0.7, edgedashstyle=[[10px, 5px], [10px, 5px, 3px, 5px], [4px, 4px], []])

The use of this kwarg should be properly documented. When vectors are passed for each edge, the values define the sequence of dashes and spaces. For example, the first edge will have 10px solid dash with 5px spacing in between; the second edge will have the following alternating sequence: 10px solid - 5 px space - 3px solid - 5 px space - etc...

```
