to_std
: standard id of edge end
value
: When a value is set, the nodes will be scaled using the options in the scaling object defined above.
title
: The title is shown in a pop-up when the mouse moves over the edge.
arrows
: To draw an arrow with default settings a string can be supplied. For example: 'to, from,middle' or 'to;from', any combination with any separating symbol is fine. If you want to control the size of the arrowheads, you can supply an object.
