Today's #TidyTuesday is an #rstats exploration of internet accessibility.

Websites are slowly improving their accessibility and use of alt-text. However, we can still do much better - particularly by ensuring that pages have colour schemes with sufficiently high contrast. ⌨️🎨

Nice chart Zak!

I wonder what happened in early 2018? I saw your commentary "I would speculate that this might be a period in which the metrics were redefined, but I wasn't able to find any hard evidence to support this."

Any #a11y #webdev experts out there know what's up?

@seblammers @zakvarty looks like guidelines updates in 2018? I don't know if this is just coincidental or if this is actually why things changed in 2018
