I just love this video! I find it so inspiring and creative. I'm always looking for ways to simplify and share genealogical and historic information. A Family Tree is a great example of an infographic. You are taking a information that is hard to conceptualize and "drawing" it out in a way to identify the different components. Men from women, generations from older generations, places of birth/death...and so on. When you visualize your family tree, you might be surprised to see connections or patterns you might not have realized without displaying information in a visual way. Another avenue of data visualization I find incredibly relevant to genealogy are maps!
See how I've visualized genealogical and family history data.
