This sample uses OpenGl to create a 3-D Scattergraph that the user can view from any angle by rotating with the mouse. The data can be shown with either orthographic or perspective projection. The data, and optionally the color of each point, are loaded from a text file. The application can be re-sized in the usual manner, and this re-sizes the graph. The slightly unusual feature is that the user can draw around points in the graph to select them, and then zoom the graph so as to magnify the region containing the selected points.
