Customising ‘top user’ widget display

This must have been asked (or explained) before, but having searched I can’t find the solution.

On my site when I use the user widget, the layout takes up a huge amount of space (see bottom image). It includes data such as best, answers questions etc

How do I make it so that it’s more compact, ideally just the avatars (like the example on the anspres homepage (image below), or reduced info like on askbug demo (which just has avatar & reputation)…

Many thanks in advance…
