Ah. Yes.

That is also an alternative. Can plot directly to plotly from R too :-)

In my case, I can't send sensitive data around - it might even be illegal, and did not want to shell out a large sum of money for my own personal instance, but for non sensitive stuff or when it's worth the money it seems to be the bees knees!

plotly.js is the MIT licenced[1] charting library released by Plotly, which you can use to create plots without shipping data to anyone else.

It can be used from R (IIRC), since the corresponding Plotly library just generates a declarative JSON plot description, which plotly.js can use.
