Pulling JSON file data for Smoothie Charts

[Manaal Siddiqui]

I would like to pull JSON data to be displayed in the output of my chart. 

Here's the code I have so far: 

HTML 

<script src="http://smoothiecharts.org/smoothie.js"></script>

<div>

    <canvas id="chart" width="500" height="250"></canvas>

</div>

javascript

var chart = new SmoothieChart({grid:{fillStyle:'#ffffff'},labels:{fillStyle:'#000000'},tooltip:true,timestampFormatter:SmoothieChart.timeFormatter}),

timeSeries = new TimeSeries();

chart.addTimeSeries(timeSeries, { strokeStyle: 'blue', lineWidth: 1 , fillStyle:'rgba(0,128,255,0.30)'});

chart.streamTo(document.getElementById('chart'), 100);

setInterval(function()

{

    timeSeries.append(new Date().getTime(), Math.random()*100);

}, 1000); 

//Math.random()*1000 to be replaced with JSON data

I do not know how to output JSON data through Smoothie Charts. I would greatly appreciate it if someone could help guide me. 

Thanks
