56 A <b>BalloonLink</b> is a custom <a>Link</a> that draws a "balloon" shape around the Link.fromNode. It will create
57 a triangular shape with the base at the fromNode and the other point at the toNode. It is defined in its own file,
58 as <a href="BalloonLink.ts">BalloonLink.ts</a>.

61 Usage can also be seen in the <a href="../samples/comments.html">Comments</a> sample.
