It seems that China blocks Google libraries, along with other Google services. This is causing problems in our courses that use math filters, since they rely on the Google Chart API to render images (https://www.screencast.com/t/jB9322q9fh0).
Wondering how other people are working around this?
Suggestions welcome!
Thanks,

Which math filter are you using? If it is just MathJax to render formulas you can get a copy of MathJax and install it on your server.
Is there in fact supposed to be a chart there with your formula? From your screencast photo I can't tell if there is supposed to be something "charted" for display.
Could you possibly use the JSXGraph filter in Moodle? You can actually get the two distributed files for JSXGraph and put them on your own server. it is amazing what you can do with it.
