//Setup some fake data
var data = [
  ['@BobBarker', 600000],
  ['@AdamWilder', 100000]
];

var aHeight = 500;
var aWidth = 500;

//Initialze the widget
var chart = d3.select('#vis')
  .append('svg')
  .attr({
    height: aHeight,
    width: aWidth
  })
  .append('g')
  // .attr('transform', 'translate(40,150)')
  .attr('transform', 'translate(0,20)')
  .chart('ComparisonBarChart')
  .c('width', 400)
  .c('barHeight', 50)
  .c('title', 'Tweets')
  .c('labelSize', 10)
  .c('titleSize', 24)
  .c({
    'width': 400,
    'title': 'Tweets'
  });

//Render the chart with data
chart._notifier.showMessage(false);
chart.draw(data);
