Yerren the code I uploaded in this post does in fact both work and validate fine so you could for now just use that if you wish. It is the code I have running on my server (although not linked to my website).
I understand that your code is primarily just a javascript program but a lot of folks here have a specific design for their sites and like all the pages displayed to be in the same format. This currently can only be added if you use an iframe or embed tags. The current implementation of the Steel Gauges in javascript do not need either of these techniques to add them to an existing design.
It would be good if in future the implementation of FreshWDL could take this on board.

That’s really awesome, thank you for that!
I think the reason it doesn’t work without an iFrame (or similar) is that it scales relative to the window.
I will see if I can change that, somehow.
