angular chart is not rendering

Hi,

I'm using the Angular Charts to draw a bar graph in my application. However the chart is not rendering. There are no errors shown in the dev tools too.

<canvas id="bar" class="chart chart-bar" chart-data="data" chart-labels="labels" width="200" height="200"></canvas>

This is bound to my main controller and the values are defined as below

angular.module('app', ['chart.js']);

I've added all the dependencies. Including the javascript files.
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.min.js"></script>
<script src="http://cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.min.js"></script>

Any help will be much appreciated. Thanks!
