We have a tool that flags images that lack an alt=
attribute. See https://help.siteimprove.com/support/solutions/articles/80000863904-accessibility-image-alt-text-best-practices -- these are essential for conveying the image contents to users on screen readers.
You can add these to your vignettes by using the recent-ish fig.alt
chunk option in knitr
; see https://www.rstudio.com/blog/knitr-fig-alt/.
There are a lot of issues, so I'll just name the vignettes:
- Edges
- Layouts
- Nodes
- tidygraph
If you'd like more details I can provide, but I'm assuming it's basically clear enough what plots are at issue.
