See this page, for example:

Depending on a browser we see one of errors as follows:

• Uncaught ReferenceError: Hh is not defined (in Chrome)
• TypeError: chart.draw is not a function (in Firefox)

JSFiddle examples linked from the documentation and attempts to work with charts manually fail with the same diagnostics.

Is there any way to work around this?

• javascript
• google-visualization

Seems to be a bad release (v44). Until it is fixed, the workaround is to explicitly specify previous version of the API to load instead of using current:

-     google.charts.load('current', {'packages':['gantt']});
+     google.charts.load('43', {'packages':['gantt']});

Please note that this will indeed freeze your charts version and you will not get new features and bugfixes unless you will revert the changes.
