example, names can be shortened to first initial plus surname, as shown
in
Figure 5-15
.

Shortening labels reduces overlap and makes the scene
much less cluttered.
Improving Label Legibility
Even with short labels and narrow fonts, some text will still be difficult to
read over lines and nodes. The readability of text depends on the amount
of contrast against the background. As shown in
Figure 5-16
, an orange
label on a purple background of the same brightness will be difficult to
read—contrast is required.
Figure 5-16:
Labels that have the same brightness (or darkness) as their
background are more difficult to read.
Therefore, if black labels are on top of dark nodes and lines, they will be
difficult to read. You can improve legibility in many ways:
•
Change colors of nodes and/or links
—Adjust the range of colors of
the underlying node to increase contrast. Following from the previous
example, brightening all of the node colors results in labels that are
easier to read.
•
Tweak node positions
—Depending on the software used, you may
find tools to automatically adjust node positions for improved label
