Delete/cleanup custom visual whenever the necessary data is not longer bound

[giorgikok]

Hello, 

I am trying to figure out why my column chart visual is not properly deleting after adding the data and then removing it. For instance, removing categories should void the visual since it can't display it anymore but the columns stay on with the last data they've received also without properly scaling to the visual window. 

I am wondering what the problem might be, the destroy() method only does sets the this.svg to null which should be enough to delete the visual from the display window.

I figured it out: just had to do this.barContainer.selectAll("*").remove(); whenever the necessary conditions for deletion were met.
