Hi Tom,

You have a few problems with your code:
  1. Specifying the values '1', '1.1', and '1.0' is no longer valid for the new loader. The new equivalent value for 1.0 is 'current', the equivalent value for 1.1 is 'upcoming', and there is currently no equivalent value for '1'.
  2. While this doesn't break anything, you no longer have to specify 'visualization' when calling .load. This is because this new loader is used exclusively for charts, and you don't need to clarify.
  3. This is really the biggest problem. You have two drawChart functions in your code. There is no way that any browser will be able to disambiguate between them. You need to give each function and variable a unique identifier if you intend to refer to it. One simple fix would be to just rename your functions to drawChart1 and drawChart2. But the better fix would be to just render both charts in one function, like I did in this jsfiddle: http://jsfiddle.net/1kkjr428/
