Graph won't show after changing css background color to blalck

My graph (scatter) stopped displaying after i changed my css rule to : *{background-color: black}
the hover effect still shows as you hover through each point

I have had this before on a polar chart - issue was I attached the background color to the incorrect ID, most graphs have multiple layers including an overlay which most likely is what was changed, use inspect element, drill down to your layers of your scatter graph and see which layer has the background color attached and attempt to change it inside inspect element to see which ID it should be allocated to

This tells all the elements of the page to have a black background color. Is that the desired behavior?

If not, consider changing it to be more pointed, or… try this:

*:not(svg) {
   background-color: black
