Change size of circle when hovering over graph

Hello everyone,

I’m currently doing some changes to the design of Grafana, mostly concerning the css.

Has anyone done that before?
Thanks in advance for any help!

Make your panel editable and navigate to visualization.
Change the point radius.

I mean the circles which are shown only when hovering over a graph, marking the values displayed by the tooltip. They are used even if the draw mode isn’t Points. The cursor cross is missing in the screenshot:
