I think (a corrected) density histogram is core functionality for unequal bin lengths.

The graph with raw count in the case of unequal bin sizes would be quite misleading when plotted and interpreted on the real line and not on discrete points (shaded areas instead of vertical lines). And as the origin of this thread showed, it's not trivial to figure out what the correct normalization is. So, I think, if we drop the density normalization, we just need a new function that does it.

(Not a dev, but ) I agree with Josef. Throwing out normalization completely would in addition have to destroy backwards compatibility. It's another question whether the frequency ( not density! ) normalization is so simple that it is better left out, since everyone can be expected to be able to do a raw histogram and divide by the number of data points without a headache.
