Why it is here

Motion that
reports itself.

Most animated charts decorate a number that was already decided. Here the width transition and the counting label are two readings of one clock, so the figure cannot arrive before the bar that earns it. The staggered entry then does the editorial work: the three parts are read in order rather than compared all at once.

The chart earns its motion twice: breaking one stacked bar onto separate rows makes a lopsided split readable, and tying each bar's duration to its own length keeps a long bar from feeling slow while the number inside it stays honest to the width.
