MindSeer has several straightforward tutorials available to walk you through the steps required to visualize your data. A good place to begin is with the Visualization Overview. It will give you an idea about MindSeer's capabilities and general organization. After going through that tutorial, you can add your own data by Creating a Library file. Other topics include plotting points in 3D ,creating a 3D surface, and client-server mode. All of the tutorials except the last use the same Sample Data.
