This is a cool way to investigate your DNA matches. Each of the dots represents one DNA match with the tester (and the bigger the dot, the closer the match), so by checking how each match connects with other matches, we can create a graph showing all the connections. Then, by running a cluster analysis on the data, we can separate out related families by colour. We can zoom in on each of these clusters and identify the best match to focus our research on, and try and potentially break through some brick walls we were unable to solve via paper records
