How to clear selection

[powerkriya]

I am enhancing the circle card visual by adding a border only when selecting the card.  Iam populating a category data field and a label field value on the visual.  Now I using this visual on a report page multiple times.  

If I click my circle card visual iam showing border for the circle and at the same time i want to remove the border on the circle of other circle card visuals on the same report page.  This is to give a feel which visual is being selected.

How to achieve this?

Iam using the below code to add the border

d3.selectAll("circle")

.attr("stroke", shapeBorderColor)

.attr("stroke-width", "2px");

I added "supportsHighlight": true in the capabilities.json and this adds the highlights array to the dataview for the visual which is not currently selected.  Using that i managed to remove the border of the circle.
