I see you have been served already; I concur with Oanh's suggestion, which generally works well.
mildly amusing, nature has an article out just now, "Open-access publishing gains another convert"---which is an article what they call 'premium content' (i.e., pay-per-view).... so you'd have to pay to read who else will give you free access...
there is also the Mathematics Genealogy Project, with Personalized genealogy posters to display your academic heritage. They are not as colourful as the one you show, but go back in time for centuries.
