The <code>RadialLayout</code> class is an extension defined at <a href="../extensions/RadialLayout.js">RadialLayout.js</a>.
|
|
The override of the <code>RadialLayout.rotateNode</code> sets the <code>angle</code>,
|
|
<code>sweep</code>, and <code>radius</code> data properties.
|
|
Bindings in the node template use those properties to produce the appropriate <a>Shape.geometry</a>
|
|
and the <a>GraphObject.alignment</a> and <a>GraphObject.angle</a> for each <a>TextBlock</a>.
