We will enter the following table into a spreadsheet.  It may be necessary to enter a space into the cells which look empty.

Then you will select the entire area by clicking on the upper left cell, then holding Shift down, then clicking on the lower right cell.

Then you will click on Insert, then on Chart, Then on Pie, then on the upper left version of the Pie chart.
