You have 6 people standing in a room. All you know is the distance they are from each other. Are there any charting utilities that will show the relative locations of each of the people?

Or, another way to put it is: 6 people have taken a YDNA test. All you know is the Time to Most Recent Common Ancestor between each two people. Can this be charted in two dimensions? 12 people? 30 people?

How would it resolve errors in measurement?
