Create a Venn diagram comparing Lincoln and Jefferson. Create the diagram. Make a circle for each of the subjects. Every circle should overlap with at least one other circle. Label each circle. Near or inside of each circle place the name of the topic or item which the circle represents. Avoid writing the titles inside neighboring circles in order to maintain clarity. It may be useful to distinguish the titles from other text by placing them in a box or altering their font or color. Enter the differences. Inside each circle place characteristics that are unique to that specific item or idea, and are not true of any of the other topics. Enter the similarities. If two or more subjects have a feature in common, place that feature in the section in which all such shapes overlap.
