Specify an additional point that a link must pass through.

A link normally goes in a straight line between the two nodes listed in the NODES configuration line. If you need it to go around something else, or to seperate two parallel links so that the bandwidth labels are all visible, you can make the link curve.

If you specify multiple VIA lines, then the link will pass through each in turn, in the order they are specified.

You can choose between curved or angled links with VIASTYLE.

Any VIA can also be specified relative to a NODE on the map. This makes it easier to have curves keep the intended shape as you re-organise a map.
