Text alignment overview

An experiment on visualizing a comparison of a pivot sequence with successive modifications of it.

All the sequences are partitioned into sections, which are colored progressively in the pivot.

In the modified sequences, the sections of the original sequence are changed in length, moved to different positions or removed entirely. New sections also appear (depicted in gray).

The use of color alone to convey this kind of information could be not enough, but has the advantage of requiring few marks to be represented, and could thus prove to be useful in an overview.
