Help: spot repairing scratched wooden floor.

I have a hardwood floor, which has been damaged by an office chair: http://ift.tt/1NzPHOT

It appears that the varnish has been scratched off, and there is minor scratching on the wood itself.

Is there any way I can "spot fix" this area?

Thanks heaps!
