-
- A tree layout in the form of a sunburst. <img
- src="../sunburst.png" width="160" height="160" align="right"> The
- center circle corresponds to the root of the tree; subsequent rings
- correspond to each tier. Rings are subdivided into wedges based on the size
- of nodes, per <a href="#size">#size</a>. Within a ring, wedges are sorted by size.
- <p>The tree layout is intended to be extended (see <a href="../symbols/pv.Mark.html#extend">pv.Mark#extend</a> by
- a <a href="../symbols/pv.Wedge.html">pv.Wedge</a>. The data property returns an array of nodes for use by
- other property functions. The following node attributes are supported:
- <ul>
- <li><tt>left</tt> - the wedge left position.
- <li><tt>top</tt> - the wedge top position.
- <li><tt>innerRadius</tt> - the wedge inner radius.
- <li><tt>outerRadius</tt> - the wedge outer radius.
- <li><tt>startAngle</tt> - the wedge start angle.
- <li><tt>endAngle</tt> - the wedge end angle.
- <li><tt>angle</tt> - the wedge angle.
- <li><tt>depth</tt> - the node depth (tier; the root is 0).
- <li><tt>keys</tt> - an array of string keys for the node.
- <li><tt>size</tt> - the aggregate node size.
- <li><tt>children</tt> - child nodes, if any.
- <li><tt>data</tt> - the associated tree element, for leaf nodes.
- </ul>
- <p>To produce a default sunburst layout, say:
- <pre>.add(pv.Wedge)
- .extend(pv.Layout.sunburst(tree))</pre>
- To only show nodes at a depth of two or greater, you might say:
- <pre>.add(pv.Wedge)
- .extend(pv.Layout.sunburst(tree))
- .visible(function(n) n.depth > 1)</pre>
- The format of the <tt>tree</tt> argument is a hierarchical object whose leaf
- nodes are numbers corresponding to their size. For an example, and
- information on how to convert tabular data into such a tree, see
- <a href="../symbols/pv.Tree.html">pv.Tree</a>. If the leaf nodes are not numbers, a <a href="#size">#size</a> function
- can be specified to override how the tree is interpreted. This size function
- can also be used to transform the data.
- <p>By default, the sunburst fills the full width and height of the parent
- panel. An optional root key can be specified using <a href="#root">#root</a> for
- convenience.
