I like the idea of having such information, so I'm in favor of these patches.
(The graphs also painfully show the time lost in all ./configure
steps, while many of the checks are identical...)
As I mentioned as comment on your patch, I think we can make this an
optional feature for those who want it.
Is it possible to have html output as an alternative to pdf? I can
also imagine that some people simply want image files, like png or
even svg, so the graphs can easily be embedded in other web pages.
