Is there a chart for A Song of Ice and Fire that is similar to these charts for Lord of the Rings and Star Wars that were made by Randall Munroe?
It would really help to keep track of the whereabouts of all characters in such a complicated series.

It only covers events up to the fourth book, and the site itself has other resources, including a unique animated time line map.
