[CentralOH] Simple XY Graphing

[Austin Godber]

Matplotlib is fantastic, I don't dispute that in the slightest.  But
as it turns out, the dygraphs library is pretty simple.  I have been
wanting to provide dynamic plots of spectra, rather than just static
image (mainly to easily enable and disable different lines).

With just some simple HTML and an already existing CSV file, I can put
this graph up in just a few seconds:
