This is the abstract base class for <code><a href="BiGraph.html">BiGraph</a></code>
and <code><a href="BiGraph2.html">BiGraph2</a></code>. If Mozilla support is needed
use <code><a href="BiGraph2.html">BiGraph2</a></code>. If line chart and/or pie chart
is needed then use <code><a href="BiGraph.html">BiGraph</a></code>.
</p>
<p>This class extends
<code><a href="BiComponent.html">BiComponent</a></code>
and therefore all methods and fields available for
<code><a href="BiComponent.html">BiComponent</a></code>
are also available for <code>BiGraphBase</code>.</p>
