Vis.js Gap between Node and its border

Using Vis.js I want to Generate something where in there is a gap between the Circular image and the Node border

Sample:

I cannot find anything at the Vis.js documentation for such a modification, can anyone guide me for it?

Solution

There's no way to achieve this unfortunelly. The color option only accepts one border and you can't make use of CSS since Vis is built using canvas, not SVG.

What you can do to achieve this is crop your image in a circular shape with some transparent padding to make the gap. And then vis would add the black border for you.
