Sorry, the desired property I would understand, but that does not click
with your "have to be independent" conclusion, so I do not have comment on
the "maybe it should be..." part.

The resolution requirement may want to set a "desired lower limit" for the
width of the graph, but it is only "desired" because it is possible that
you have to bust the limit if you have three files with 1, 9999 and 10000
changed lines and your terminal is only 200 columns wide.

The current code caps name part to 50/80, but allows the graph to use more
when you have only shorter names.  Perhaps you can follow the same logic
in the first part of your [7/8] (which needs to be separated to at least
in two pieces, as it conflates the "lift 50-column cap from the name width
and make it proportional to the term_width()" part and "but cap the graph
part to 40-column" part, that are separate topics)?  Then we can try
different heuristics to find a better way to cap the length of the graph
on top?
