Ah shit, that should not happen and I think that's on Google's end. Just in case, what device and browser are you on?

Thanks for letting me know and the nice words!

I have the same issue: Linux Desktop + Firefox 60

Chromium seems to display all charts without any problems (same computer).

Btw. it looks like once a chart has been loaded successfully, it is cached so that you have to clear/disable the browser cache in order to see the issue again.
