Looking forward to your feedback!
No, we never thought about HTML output. However, there are multiple other export options and we also ship Python scripts that can be used to plot the benchmark results. The script is not very large, so far, but we are happy to add new scripts if the need for one should arise. What kind of diagrams would you like to see?
Also, I have never thought about using criterion.rs. My feeling was that it is suited for benchmarks with thousands of iterations, while we typically only have tens of iterations in hyperfine (as we typically benchmark programs with execution times > 10 ms). Do you have anything specific criterion feature in mind that we could benefit from?
I ask purely as a comparison to some of the design choices bench made for personal edification.
That being said, one of the hypothetical advantages of using criterion is that you get to piggy-back on its visualizations and statistical analyses, which are quite useful for showing friends and coworkers. I'm not sure of the specifics of how you're doing outlier detection, but Criterion's method is quite nice and I find the choice of linear regression for linearly increasing iterations to be an interesting sanity check.
Criterion can work for lower iterations as well (although tens is definitely getting into the lower bound).
