+<h1>Resizing Diagrams</h1>
+<p>
+  Sometimes it may be necessary to resize the div that contains a GoJS Diagram.
+  In older browsers or in Internet Explorer, GoJS does not listen or attempt to detect changes in the div's size,
+  so you must manually tell each Diagram when you perform an action that resizes its containing div.
+</p>
+
+<h2 id="UsingRequestUpdateToResizeDiv">Using <a>Diagram.requestUpdate</a> to resize a Div</h2>
+<p>
+  The following example has a button that enlarges the Diagram's div. When it is clicked,
+  the div is visibly resized but in older browsers the Diagram remains the same size.
+</p>
+
+<pre class="lang-js" id="first">
+    // A minimal Diagram
+    diagram.nodeTemplate =
+      $(go.Node, "Auto",
+        $(go.Shape, "RoundedRectangle",
+          new go.Binding("fill", "color")),
+        $(go.TextBlock,
+          { margin: 3 },  // some room around the text
+          new go.Binding("text", "key"))
+      );
+
+    diagram.model = new go.GraphLinksModel(
+    [
+      { key: "Alpha", color: "lightblue" },
+      { key: "Beta", color: "orange" },
+      { key: "Gamma", color: "lightgreen" },
+      { key: "Delta", color: "pink" }
+    ],
+    [
+      { from: "Alpha", to: "Beta" },
+      { from: "Alpha", to: "Gamma" },
+      { from: "Gamma", to: "Delta" },
+      { from: "Delta", to: "Alpha" }
+    ]);
+
+    // Resize the diagram with this button
+    var button1 = document.getElementById('button1');
+    button1.addEventListener('click', function() {
+      var div = diagram.div;
+      div.style.width = '200px';
+    });
+</pre>
+<div id="dia1"></div>
+<p>This button won't work in Internet Explorer: <button id="button1">Expand div</button></p>
+<script>goCode("first", 100, 110, go.Diagram, "dia1")</script>
+
+<p>
+  Typically we will want the Diagram to resize to its div at the same time that the div resizes.
+  To do this we add a call to <a>Diagram.requestUpdate</a> <em>after</em> we have resized the div.
+  This checks to see if the Diagram's div has changed size, and if so, redraws the diagram at the appropriate new dimensions.
+</p>
+<p>
+  Below is nearly identical code, except that a call to <a>Diagram.requestUpdate</a> has been added.
+</p>
+
+<pre class="lang-js" id="second">
+    // A minimal Diagram
+    diagram.nodeTemplate =
+      $(go.Node, "Auto",
+        $(go.Shape, "RoundedRectangle",
+          new go.Binding("fill", "color")),
+        $(go.TextBlock,
+          { margin: 3 },  // some room around the text
+          new go.Binding("text", "key"))
+      );
+
+    diagram.model = new go.GraphLinksModel(
+    [
+      { key: "Alpha", color: "lightblue" },
+      { key: "Beta", color: "orange" },
+      { key: "Gamma", color: "lightgreen" },
+      { key: "Delta", color: "pink" }
+    ],
+    [
+      { from: "Alpha", to: "Beta" },
+      { from: "Alpha", to: "Gamma" },
+      { from: "Gamma", to: "Delta" },
+      { from: "Delta", to: "Alpha" }
+    ]);
+
+    // Resize the diagram with this button
+    var button2 = document.getElementById('button2');
+    button2.addEventListener('click', function() {
+      var div = diagram.div;
+      div.style.width = '200px';
+      diagram.requestUpdate(); // Needed!
+    });
+</pre>
+<div id="dia2"></div>
+<button id="button2">Expand div</button>
+<script>goCode("second", 100, 110, go.Diagram, "dia2")</script>
+
+<p>See also the <a href="../samples/tabs.html">jQuery Tabs sample</a>.</p>
+
+<p>
+  In recent browsers the calls to <a>Diagram.requestUpdate</a> will not be necessary,
+  but they will not cause any harm.
+  Still, if you know that all of your users will be using recent browsers
+  and if you are using GoJS version 2.1.26 or later, you do not need to make this call.
