Plot diagram is also called the structure of the story. It is the main outline of what is going on and everything else exists solely to support that structure. There are a couple of different types of plot structure but the basic one consists of Exposition, Rising Action, Climax, Falling Action, and Resolution. Learning Through Listening explains each of the five elements of plot and even breaks down the Cinderella story to help make it even more understandable. Exposition sets up the story and lets the stakes become known, Rising Action is the problem and/or conflict the character attempts to resolve, Climax is where the story is at it's worst, Falling Action is where the character begins to solve the problem, while Resolution brings the story to a close in some manner. Exposition, Rising Action, and Climax (or beginning, middle and end) is what is called the 3 acts of a story, each plays an important part to the story.
