Does this have a different name in LaTeX? I tried searching for pictograph or pictogram plot, with no luck... It can't be that hard to make it with pgfplots, or is it?
@G.Bay pgfplots is probably over engineered for that, you just want to repeat \includegraphics n times which you don't need any package for, use \prg_replicate:nn or \int_step_function:nnN or \multiput all of which are defined in latex and don't need any package.
@CarLaTeX we should have roast dinner to celebrate
