Data as imported into a CPG application table. Data are most conveniently assembled in a spreadsheet and then saved as tabbed text or .csv format. The left-most two columns are the complex categories, with the overall complex name in column one (green) and the subunits in column two; the number of subunits in column two is used to provide the correct number of sectors in the pie chart. A space/empty cell separates each system. The top four rows contain the taxonomic information. The top level is used to define colors for groups of pies (red), and the remaining are for labeling only. In the example in Figure 1 the fourth row is unused. Below these rows is the data matrix (blue). All cells corresponding to a subunit must be filled and empty cells are not allowed.
