bright cyan outlines require effort to visually scan across all the boxes to see
them.
Figure 5-28:
In this representation of occupation data, node fill color
indicates income change, and node outline color indicates overall income.
Note that the outline colors do not visually pop out.
In general, care is required when adding many extra data attributes. Ensure
that the most important data for the objective incorporates the visual
attributes that visually pop out (such as size and node fill color). Don't
add extra data that isn't relevant to the analysis. In the occupation income
example,ifchangeinincomewasnotimportanttotheobjective,youcanuse
node fill color instead for the important attribute.
When you have many equally important data attributes and you use them
as support for successive points in an analysis, you might consider using
two images or three images. In each case, use a consistent layout, but then,
in successive versions, vary the attribute of interest. For example,
Figure
5-29
shows the occupation data first colored by change in income and then
colored by median income.
