Here I'm getting a "This embedded plot has reached the maximum allowable views given the owner's current subscription"

Oh man, here I thought that surely whatever needed for plotly is self-hosted.

Seems like a decent thing, first impression (it works for me) was that this might actually be one of the very few things that javascript seems to improve upon the old web.

But I can't fathom how anyone could pay to make their website useless.

Do an automatic to static image failover and also provide an option at the top of the page to do this manually if it for some reason doesn't work (or isn't worth it / making the site slow). Also self host it. Anything less and you couldn't pay me to use it.

EDIT: Actually, it should probably be static image first and then "click to make dynamic" for the rare cases when you actually would want it to be.
