Map of Greek Island Ferries

I'm wondering is there anything like Flight Connections for Greek Ferries? Something that can show you all the different routes between all the islands like Flight Connections does for flights? I have tried Googling but the results I get are all company specific, it would be more convenient if there was one website where I could see them all.

You can see potential ferry routes on a map e.g.

but the only 'database' sites for all island ferries that I'm aware of are consolidation websites such as:
