The Uniqueness of the 4th Gospel

I was surprised to learn that over 90% of the Gospel of John is unique. Here's a chart I made detailing the material that is included in the Synoptic Gospels (Matthew, Mark, and Luke), but is not included in John's Gospel and vice versa. Thanks to Bible.org for all of the articles that allowed me to compile this information.
