The pprof tool helpfully provides a -http flag that opens a web page with an interactive view, but there's no easy way of telling what elements of the UI mean or do. For example, it would be useful to have a key to the diagrams to say what the numbers mean and what's the difference between a dotted and a solid line, etc.

As it is, the user is left to google for potentially relevant articles blog posts that might or might not be out of date now.

At the very least, a link to an online documentation page would be good, although that might suffer from potential version skew if the URL isn't versioned.
