The absurdity of categories (histograms)

Example: household expense categories.

Too coarse: no information
Too fine:   no information

There seems to be no intrinsic way to decide what level of detail is
good enough.  However, there is definitely some level of detail that
makes "most sense" in some handwavy way.

Where exactly does the sweet spot come from?

Is understanding nothing more than applying appropriate courseness to
minimize some kind of connective / organizational property?
