Carnegie Mellon's Six Degrees of Francis Bacon

Carnegie Mellon University and Georgetown University have created "Six Degrees of Francis Bacon," a digital humanities project that recreates the British early modern social network to trace the personal relationships among figures like Bacon, Shakespeare, Isaac Newton and many others. The website lets academics, students and anyone else interested in this period view and add to the network. The site currently identifies more than 13,000 individuals and highlights approximately 200,000 relationships.

I don't think there is a time-inflected view, but it seems you can choose earliest and latest dates for the people you are interested in.

And, importantly, there is a level-of-confidence selector, so you can choose whether to look only at certainly documented relationships or those that are less sure. If only more historic visualisations were honest about uncertainty!
