A Bar chart showing Google's power usage

Here's a chart that was recently shown on Googles blog and I decided it would be a great one to recreate with RGraph. It uses the canvas library but it should be equally as simple to use the SVG libraries.

It's a stacked Bar chart which uses the labelsAboveSpecific option so that the labelsAbove labels can be specified explicitly.

The Y labels are specific, enabling the top label to have some text appended to it.

There's a key that's positioned on the left-hand-side and also a title that's positioned in the same place.

Also the Y axis is disabled, the X axis is colored gray and its tickmarks are disabled.

The responsive() function changes the size of the chart, changes the size of text on the chart and changes the key to be in the bottom right corner of the chart. It gives the key a semi-transparent white background too so that it's easier to read.
