Visualizations are not rendering

Let me first stat that I'm new to Power BI. Using the Power BI Desktop, I've not been successful using the DIAD lab, I've not been successful at generating a visualization for anything. When I go to create dashboard and add visualizations the charts/graphs do not generate. All I get is a representation of a spinning courser in the upper left of each visualization. I've tried this on two different machines, both using Windows 10 enterprise. I know this is not much to go on but I don't know where to start looking. One of the instructions indicated he had seen this before but could not point me in a direction for resolution. Any ideas are appreciated
