It is possible to define custom JointJS elements with hyperlinks
pointing to external sites - by including the <a>
SVG element
in the markup of a custom element.
The navigation path is then specified in individual elements' attributes of the custom type.
The two most important XLink attributes in this context are the following:
xlink:href - set the target resource URL.xlink:show - how should the linked content be presented?
Possible values are 'replace' (show in current window; default) and 'new'
(show in new window).JointJS source code: hyperlinks.js
