+These can be used to communicate parts of a whole for categorical quantities.
+To emulate the percentage view of a pie chart, a 10x10 grid should be used.
+In this way each square is representing 1% of the total.  Waffle provides
+tools to create charts as well as stitch them together.  Isotype pictograms
+can be made by using glyphs.")
