How to add xlink to box chart?

Is it possible to add xlink for Box plot?
Examples for links are for Bar chart - where link is connected to particular value. I'm looking for a way to assign link to whole box with Min, Max etc values. Probably one could re-edit svg file. But maybe pygal can insert such link?

Start by comparing how links are handled for Bar charts with how Box plots render their boxes and values. Determine whether pygal can attach an xlink to the whole box in the generated SVG, and define the expected behavior for boxes containing Min and Max values; the issue names no files or tests to run.
