Giving Elevation Height in Google Maps

One of the most interesting presentations at this year's Google I/O was about Google Maps visualisations using the new CanvasLayer library. That presentation included an interesting demonstration of using the CanvasLayer Library to add elevation height along a path.

Fuzzy Tolerance has decided to recreate this functionality using SVG symbols. What's more they have been kind enough to share the code as well. Using SVG in this way provides a nice alternative for map developers to actually display elevation along a route on the map rather than as a separate elevation chart beneath or beside the map.
