Hi Ninette,

Firstly, thanks for these patches, it is great to be able to try and
improve these and make the data more usable and interactive.

To help others visualise the new output and test the patches I've made
a test run on the autobuilder and the results are:

http://autobuilder.yocto.io/pub/non-release/20240413-21/testresults/buildperf-alma8/perf-alma8_master-next_20240413135138_904bb385c3.html

and

In general I love the wider commit range of the new chart and that you
can interact with them, this is great.

The is one big problem which is the change to "start_time" which is
problematic. We need the commit numbers on the graph to be able to
decode which change a given point in time represents. Is there a way we
could show both the commit number and date of the build together?

I think if we could fix that issue these would be good to merge from my
perspective. I have shared links to the examples above in our weekly
status report for others to review as well though.

Cheers,

Richard
