Trigger click via javascript

Hello,

I’m playing around with the sunburst chart. I wonder if it is possible to virtually “click” on any of the elements by code. Lets say you are looking at a zoomed level and want to go back one step. And since not everyone understands that they have to click in the middle, I’d like to offer a back button to go one step back. Going to the root would be simple, but one step back seems to be not possible.

I also wanted to have a tree element next to the sunburst. So when activating a tree element, I’d like the same element to be in the center of the sunburst. But I can’t send a click to the sunburst.

Any suggestions?

Thanks so much,
Guenter
