Figure 13-8
shows an example result of clicking on Texas. Curved links
always flow in a clockwise direction, so here it is clear that Louisiana
receives far more goods from Texas than it sends. This more general trend
between Texas and other Southern states can be seen in the link rose
visualization as well, but interactions reveal variance in the pattern across
specific states.
