The Simg library created and suggest by Mauvis Ledford above worked great for allowing my svg charts created with Dimple to be downloaded.

I did however need to change one aspect of the code to make it work. Inside of the toString() prototype, inside the forEach loop (line 37), if you change "svg.setAttribute(..)" to "svg[0].setAttribute" it will alleviate the "setAttribute(..) is not a function" error. Similarly the same needs to be done right below in the return statement, appending "[0]" after svg (line 39).

I also had to manually edit the "canvas.width" and "canvas.height" (lines 48 & 49) assignments in the toCanvas() prototype, in order to make the downloaded image a more correct size (it was previously just downloading a static 300x150 square in the top left corner of the chart).
