<h2>Javascript</h2>
<p>Create a <code>Graphic</code> instance.</p>
<pre class="code prettyprint">var mygraphic = new Y.Graphic({render:"#mygraphiccontainer"});</pre>
<p>Create two path elements for end shapes. Give each a red fill and a black stroke.</p>
<pre class="code prettyprint">var diamond1 = mygraphic.addShape({
type: "path",
stroke: {
weight: 1,
color: "#000"
},
fill: {
color: "#f00"

type: "path",
stroke: {
weight: 1,
color: "#000"
},
fill: {
color: "#f00"
}
});</pre>
<p>Create a path for the connecting segment. Give it a black dashed stroke and no fill. The <code>dashstyle</code> property of the stroke attribute allows for the creation of a dashed stroke. The first value is
the length of the dash and the second value is the gap space between dashes.</p>
<pre class="code prettyprint">var connector = mygraphic.addShape({
type: "path",
stroke: {
weight: 1,
color: "#000",

<p>Draw the first diamond.</p>

diamond1.lineTo(80, 40);
diamond1.lineTo(100, 60);
diamond1.lineTo(80, 80);
diamond1.lineTo(60, 60);
diamond1.end();</pre>
<p>Draw the connector segment.</p>
<pre class="code prettyprint">connector.moveTo(100, 60);
connector.lineTo(450, 220);
connector.end();</pre>
<p>Draw the second diamond.</p>
