I'm a bit surprised at the first "cool slop" example, I'd expect a "more tangible" (by way of animation) data flow visualization to be useful rather than fluff. Though since it's not dynamic (it's not based on live data or anything), maybe that's why it'd be superfluous?

It's superfluous because the arrow already points in a direction; the line animation doesn't tell you anything the arrowhead doesn't.

On the example animation not all paths are taken, so that is one bit of extra information that the animation does provide. Though even if it was fully identical, I do find it considerably easier to see where the data is moving based on dots tracing out a path than I do by scanning for small arrows in a massive diagram, hence my confusion on this. Fair point though.
