I've added a new type of chart on reverse dependencies pages on lib.rs .
I've analyzed how dependencies change over time. Specifically, I note when crates change their dependencies, and stop using some of them. This lets me graph dependency additions and removals over time.
I've used this data to make a chart of "active" reverse dependencies over time. By active I mean crates when they use a given dependency, and haven't removed it (yet) in a later release. Additionally crates stop being counted as actively using a dependency when they appear to be abandoned themselves.
For crates that are dead, this gives an armadillo-shaped charts! Here's the gcc crate
and here's one for rustc-serialize :
and here's serde doing well :
The data also shows how failure is getting dethroned by thiserror/anyhow .
I'm very happy how clear this data turned out. Download numbers don't show these trends clearly, e.g. the obsolete gcc crate has still 130K downloads per month! The cc replacement has 6 times more downloads now, but 57 times more active reverse dependencies.

This is awesome!

This makes me think of playground's "we include the top 100 crates" threshold, which I think is currently by downloads. Maybe there's a way you could turn your new metrics here into a better top-100? (Something that would still change slowly, maybe "new reverse deps in the last year" or something, re-evaluated with every stable release?)

Nice tool! What is your definition of "abandoned" in
Additionally crates stop being counted as actively using a dependency when they appear to be abandoned themselves.

For purpose of this chart currently crates stop being counted as active 1 year after their last release. I'll be tweaking it to use a better estimate, taking into account frequency of releases, whether it's >1.0, maybe maintenance badge status, etc.

Wow, this is a really powerful tool. The graphs look like a much better measure of popularity than things like recent or total downloads.
Thank you.

I've tuned the algorithm a bit and applied it as a ranking factor now.

gfx got deprecated in favor of the lower-level gfx-hal by the gfx-rs team.
The spiritual successor of gfx is wgpu , but it's also worth noting that most users that'd tough out using gfx rather than something even higher level will probably also use gfx-hal.

It would be interesting to see per version armadillo breakdown of revdeps.
Take for instance, https://lib.rs/crates/time/rev
Its pretty clear that 0.2 is quite unpopular vs 0.1 and people aren't motivated to migrate.
And crates.io really doesn't do it justice:
