Make the GitHub contribution chart accessible
With the recent acquisition of GitHub, I am hoping Microsoft can help to make parts of it more accessible. The contribution chart in particular is a mess. It is completely keyboard inaccessible, its hit areas are too small, it offers no cues for what is interactive, its contrast is poor, it is not exposed to screen readers in any way, and it is not even responsive.
As a coding experiment I outlined these issues and made a WCAG 2.1 AA compliant version and shared it with GitHub in the hopes they would use it:
Thanks for your enthusiasm for accessibility of GitHub and for passing this on to us following the recent agreement to purchase GitHub. At this time, please continue to share feedback with GitHub directly at the Contact GitHub page (https://github.com/contact).
