The dot plot has been used for years as a simple exploratory method to visualize small discrete datasets.
A simple but effective way to display data, the dot plot has been used for hundreds of years as a way to visualize small discrete datasets. Often they are hand drawn. Attempts to re-create the traditional hand-drawn plots by computer systems typically result in approximations using the histogram chart format. Using Mathematica's advanced computational capability we can quickly re-create the exactness of the hand-drawn plots.
