From: Mapping co-ancestry connections between the genome of a Medieval individual and modern Europeans

Network of identity by descent (IBD) blocks longer than 6 cM shared between present-day Europeans (nodes). There is a link between any pair of individuals sharing at least one IBD segment. Individuals are labeled according to the population of the Human Origins. Isolated IBD pairs of individuals are not represented for clarity, with the exception of Maltese and Sardinians.
