<p>An Overview is a <a href="Diagram.html">Diagram</a> that displays all of a different diagram,
with a rectangular box showing the viewport displayed by that other diagram.</p>
<p class="box">
For more discussion, see <a href="../../intro/overview.html">Introduction to Overviews</a>.
See samples that make use of Overviews in the <a href="../../samples/index.html#overview">samples index</a>.
<p>All you need to do is set <a href="Overview.html#observed">Overview.observed</a>.
For example:</p>
<pre><code class="hljs js"> <span class="hljs-keyword">var</span> myDiagram = <span class="hljs-keyword">new</span> go.Diagram(<span class="hljs-string">"myDiagramDIV"</span>);
. . . other initialization . . .
<span class="hljs-comment">// create and initialize the Overview:</span>
<span class="hljs-keyword">new</span> go.Overview(<span class="hljs-string">"myOverviewDIV"</span>).observed = myDiagram;</code></pre>
<p>The Overview draws what the observed Diagram is displaying,
so setting or modifying any diagram templates or template Maps has no effect.
At the current time methods such as <a href="Diagram.html#makeImage">Diagram.makeImage</a>,
<a href="Diagram.html#makeImageData">Diagram.makeImageData</a> and <a href="Diagram.html#makeSvg">Diagram.makeSvg</a> do not work on Overviews.</p>
