What just happened?

We changed the chart type to the 2D Column chart as it brings out the background image much better. In a 3D chart, the canvas would come in the way of the image and removing the canvas is not an option as that would leave the columns hanging in thin air. After finding a nice image to go with the chart, we removed the background color of the chart and made the canvas of the chart transparent to get a full view of the currency notes.

To add a background image, all we had to do was specify the relative path of the image to the bgImage attribute. Due to security restrictions, your image file has to reside on the same sub-domain as the chart file and a relative path to it has to be specified. Thereafter, we reduced the transparency of the image using bgImageAlpha so that it did not hinder the comprehensibility of the chart. Finally, to get the image to fit proportionately on the entire chart, we set bgImageDisplayMode to fit. There are other modes that you can select from as well: Stretch, Tile, Fill, and Center. You can either pick any of these modes or manually set the scaling and alignment of the images using the attributes discussed at www.fusioncharts.com/docs | Quick Chart Configuration | Chart Border & Background.
