Should be pretty minimal, if the only interactivity is the mouse-over?

I think the URL tagging will be the most valuable aspect, so we can have a clear picture of traffic sources. @jiwalker-usgs do we have a url yet? will it just be vizlab/gages-through-ages/ ?

Also, all outbound links/media icons

Interaction events in javascript

outbound links can be baked into templates? Should be reusable

Tagged URLs for later:
https://owi.usgs.gov/vizlab/gages-through-ages/?utm_source=facebook
https://owi.usgs.gov/vizlab/gages-through-ages/?utm_source=twitter
https://owi.usgs.gov/vizlab/gages-through-ages/?utm_source=usgswebsite

I think there isn't a problem with using URL shorteners with these, as long as the tag is attached before you shorten the URL.

@eread-usgs or @lindsaycarr are there other source we would want to tag? We could tag different twitter accounts separately if we wanted.
