Nadieh Bremer and Shirley Wu created a data visualization of ten royal families of Europe. The screenshot here is just a portion; it actually goes back to around 1100 A.D. You can manipulate it to show how the royal families are related to each other. The largest dots are the current monarchs. Just place your cursor on a dot to identify the royal family member. If you hover over a dot long enough, you’ll get a colored visual showing how closely that person is related to other royals across the chart. If you click on two dots, you get the shortest connection between the two. I found out the royal families of Monaco and Liechtenstein don’t marry into other royal families that much, while King Harald V of Norway is related to just about everyone, including second cousin Queen Elizabeth II.
If you can find Queen Victoria of England, she appears to have the most royal descendants of all. You can read more about the data and how the project was done at Bremer’s website and Data Sketches. -via Digg
