The text rendering of Native Histograms in the Table view is quite verbose, but it's currently the only way of displaying Native Histograms in the built-in UI.

It would be cool to also display them in the Graph view rather than only in the Table view. The most obvious way of representing them would be a heat map, but maybe there are others.

A heat map can only show one histogram series at a time, so a query that yields multiple histogram series needed to produce a number of heat maps, which is distinctly different from what we do so far, namely redering many graphs in a single panel. Plus, there is the case of mixed histogram and conventional float series, for which we probably would need to render the conventional graph panel followed by n heat maps.
