Assuming this is just a refactor to pull out a base zoom class to use in other vizs?

[anandtiwary]

Sorry I meant to post this but got distracted. The only code change I did (apart from refactor) is

    this.setZoomScale(Math.min(1, Math.max(this.minScale, minOverallScale)));

to

 this.setZoomScale(Math.max(this.minScale, minOverallScale));

But this is not required since the brush feature addition. I have verified it. And I will be making some more changes to this in the next few days.
