A comparison-contrast organization charts do just about what you would expect them to with a name like that: they are useful for looking at two concepts and determining how they are similar and how they are different. The following compare and contrast organization chart is created using EdrawMax Online and shows two different books under two different color schemes, green and pink. These two charts compare two books based on a book title, book's author, and the theme of the classic literature. As the chart below suggests, compare and contrast charts have sections for the two ideas' shared common traits or similarities.
