A scatter plot represents a single data point with one mark (point) for every data point a visual distribution of the data can be seen. A scatter plot show positive or negative correlation. We chose to do a scatterplot for the comic book orders because the Est. sales have a positive correlation but the numbers are very far apart. A scatter plot is used to show a cluster, not the distinct point of the value.
