See also StatCVS-XML (http://statcvs-xml.berlios.de) and SvnStat (http://svnstat.sourceforge.net), both derivatives of StatCVS, with a few plots/charts added. If you know other graphical SCM statistics tools, please mention them.
Would additional "stats" view help? Does some bit of stats help (well, besides diffstat in commitdiff; perhaps later graphical diffstat in gitweb)?
For example all (I think) above projects include plot of "size" (usually in lines of code) of repository versus time, sometimes split into few top authors or few top subdirectories; sometimes limited to some subdirectory or even to some file only, together with the plot of "commit volume" (usually number of commits per unit, e.g. number of commits per day, but it could be numbers of files changed and/or number of lines added/deleted) vs time. Tags are marked on the time scale. This supposedly helps to realize if project/part of project/individual file is in development, refactoring or maintenace stage. And graph with different top authors plotted using different lines visualises which were active during which point of project history. I'm not sure what "commit volume" plot tells us.
Next there are various tables and plots gathering statistics about authors: lines of code + percentage, numbers of changes (commits) + percentage, average number of lines per change, ratio of modifications to adding new code. Git has git-shortlog for creating similar summary. That probably helps to realize who takes what part in development of project. And there can be similar tables, charts and plots but with module/subdirectory/file instead of author. For example top files with respect to size, changes, or number of revisions in history.
Then there are IMVHO not very useful (except for satisfying idle curiosity) histograms of activity (either number of commits, or number of changed lines) per hour of day, or per day of week, or per month of year (in older projects).
There are some other plots, charts, tables, graphs... Please do tell which ones would be good to have in gitweb.
BTW. we most certainly would have to use some cache I guess... and we have just removed the need for temporary files for creating diffs...
