What problem are you trying to solve?

gstatic.com is extremely slow from mainland China, using gstatic.cn is way much faster
you can compare the speed using https://www.dotcom-tools.com/china-firewall-test
https://www.gstatic.cn/charts/loader.js => less than 1 second
https://www.gstatic.com/charts/loader.js => at least 50 seconds

Describe the solution you'd like

on line https://github.com/rakannimer/react-google-charts/blob/master/src/hooks/useLoadGoogleCharts.ts#L31
provide option to developer to choose either get loader.js from

https://www.gstatic.com/charts/loader.js

or

https://www.gstatic.cn/charts/loader.js

Hey @51yu,

Thank you for the suggestion, I added support for changing the URL for this loader:

chartLoaderScriptUrl

You can try it out in 5.1.0
