Domain Linking Map - Network Overview needed

I have a list of 70 top level domains and I need to generate some sort of visual presentation how the domains link to each other. One domain could be in the center because the website links to all other domains, but not neccessary. And it is likely that the other domains link to each other too.

This could be either a world map (I have the country each domain is located in) or something like a mind map/network overview, examples attached.

Do you know a tool or website which can do this (incl. link checking)?
Any help or idea is appreciated!
