Question: I need disable tooltip in google geo chart. I tried `tooltip.trigger: 'none'` and other tries, but I can´t disable tooltip.

How to disable tooltip in google geo charts?

Thank You

Answer: 
Had a look around and tried a few things but it seems that this particular bit of functionality is not part of Geo charts. With other charts, you can do the following and have tooltips disabled:

```
var options = {
    tooltip {
       trigger: 'none'
    }
};

```

A [workaround I came across is to create a `div` that just sits on top of the map](https://groups.google.com/forum/#!topic/google-visualization-api/wwz_Fhs8ah0) and that disables the interactivity of the map. Not the best solution but a work around until it's made available. You can see it working on [jsfiddle](http://jsfiddle.net/cchana/JspTt/).
