interactive plot does not render if you cannot access the Google Font API

[Andy7475]

I've just discovered this as my work firewall don't allow get requests to google APIs, and so I can't render an interactive plot.
I can manually install the Roboto font family though, but the code doesn't look for it - it goes straight for the API and throws an error if you can't connect.

I have used it behind a firewall and it does work, but I think you need to specify a generic font family instead (e.g. "serif"); it has been a while though, and changes have happened to the codebase since then, so I'll have to double check that there are reasonable workarounds.

Thank you! Only impacts interactive plot. I get a lot of warnings on static plot but it does work for that.
