Let's say a user wants to check MediaWiki core metrics about code review (true example, see T107562#1579585). It won't be easy to find them, and there is no static URL to rely on.
http://korma.wmflabs.org/browser/gerrit_review_queue.html contains the list of repositories, and the only way to check the data of a specific repository is to click page after page until finding it.
This page a search box, but it ends in the project page directly, where such data is not found. http://korma.wmflabs.org/browser/repository.html?repository=gerrit.wikimedia.org_mediawiki_core is a static URL, but it is not helpful to find the graphs we are looking for.
The ideal solution would be to add these graphs to the project pages.
