This shows an overview of yEd.
GraphML is the native file format for yEd. You can export GraphML formats
from other graph software and import them into yEd. yEd also has direct
Excel import functionality, including the capability to directly import an
adjacency matrix or node/edge lists.
You can compute a few graph statistics from the Tools menu and directly
apply them to node attributes such as color.
yEd has some effective and popular layout algorithms. Some of yWorks'
graph layouts are embedded in Cytoscape. One part of yWorks' business is
selling the graph layout algorithms for embedding into other software. The
Organic Layout is a force-directed layout. Other layouts (such as Hierarchy,
Circular, and Radial) can be effective with some graphs.
One of yEd's powerful features is layouts for edges. After the nodes have
been positioned, try some of the edge layouts. For example, Organic can
subtly bend lines to avoid overlapping lines with nodes that they do not
connect with, as shown in
Figure 7-28
.
Note how the link from Drew to Trey
bends around the other nodes.
