<p>JSON data formatted according the the City Index API spec can be read in directly by jqPlot thorugh the use of the dataRenderer option and a custom ciParser data renderer.  The ciParser data renderer will translate either a JSON encoded string or JSON object.</p>

<p>To use the the ciParser, include the <code>jqplot.json2.js</code> and <code>jqplot.ciParser.js</code> files.  Specify the <code>$.jqplot.ciParser</code> as the renderer in the plot's "dataRenderer" option.  The City Index JSON data can then be passed into the jqplot function as shown in the examples below:</p>

<p>Here, a stringified JSON data objects is passed into the jqplot function.</p>
<div id="chart3" style="height:200px; width:400px;"></div>
<pre class="code"></pre>
<p>This example uses the same City Index data format, but passes in a JSON object instead of a string.</p>
<div id="chart4" style="height:200px; width:400px;"></div>
<pre class="code"></pre>
