Include both 'bar-graph.css' and 'bar-graph.js' to your document.
Create 'div' to contain your graph and give it an id.
<div id="my-bar-graph"></div>
var options = {
// id of elem that chart will be appending to
elem: 'my-bar-graph',
// background color of the graph
backgroundColor: 'red',
// increment between each step
increment: 5,
// overall width of graph (default: 100%)
width: 500
};
