It's slightly out of date, I guess. The board has no
built-in graphics, but it has PCI so you can plug in an
emulated PCI card. From that set, VGA cards will work
with TCG but not KVM (because of the memory-attribute-clash
problem); virtio-gpu should work with both TCG and KVM.

I've never tried to use graphics with the virt board (having
no need for it), but I believe it ought to work. Feel free
to experiment and update the wiki page accordingly.
