Figure 16-4: If the graph is small enough and nodes are large enough,
icons can be embedded inside of circles, enhancing or complementing what
is being shown by color.
Standard iconic symbols are an ideal choice but seldom available for the
types in the data being represented. Fortunately, to be useful, symbols do
not need to be immediately recognized by everyone. The reality is that
the representation of only a small percentage of icons is instantly clear,
such as the gender icons used here. Most icons require some degree of
interpretation. Interpretation of an icon typically involves basic knowledge
of the nature of the data, as well as inference as to what the symbol might
map to in that context.
