I noticed the alt text on the IPC flow graph. Yeah, it sucks that a plain string isn't adequate for describing those kinds of images. FWIW, since that image is an SVG, there are ways of rendering it as a tactile graphic, if one has access to the right hardware (e.g. an embosser). There's even a tutorial on writing SVG by hand, targeted at blind people wanting to produce tactile graphics. blindsvg.com/

Anyway, thanks for thinking about describing the image.
