Figure 4-11 shows an updated image of our mindmap that, again, uses our
default layout. Clearly, this is an improvement, but we still have some tweaking
to do. Note that although the left-to-right anchor and layout have been imple-
mented, we need to modify the implementation if we are to support right-to-left
layout as well.
