When i am drawing scatter plots, each point is usually a single dot. Different clusters of points are different colored dots. The size & color of the dot is set by using pen size or marker size commands, and color commands. In some cases, there is only one point of a different color that must be displayed, often indicating the centroid of a cluster, or some other single point in the space. These single points are usually dots, much the same size as other dots around it, but of a different color. Markers also work for this as well.
It would be especially nice if I could associate an ascii label to specific dots, to help identify certain attributes of specific points in the space (centroid1, outlier3, etc.) Finally, it would be great to associate weights with a series of points, which would adjust the dot size of each point. This would indicate the size of the population, or the strength of each point in the space.
