x-y-z point data can be input into the program through the "point" dialog. For a set of point, the color can be chosen and the radius of a representing sphere before the data is read. In this way the data set can all be represented uniformly. Also, once the data is in, the individual properties of the points can be changed by selecting the specific point from the scrollbar and adjusting its properties.
The result of the visualization can be several data sets differentiated by sphere size, color, and "landing" position in the x-y plane.
