Infographics are interesting–a mash of (hopefully) easily-consumed visuals (so, symbols, shapes, and images) and added relevant character-based data (so, numbers, words, and brief sentences).
The learning application for them is clear, with many academic standards–including the Common Core standards–requiring teachers to use a variety of media forms, charts, and other data for both information reading as well as general fluency...
"The connection between mathematics and art goes back thousands of years. Mathematics has been used in the design of Gothic cathedrals, Rose windows, oriental rugs, mosaics and tilings. Geometric forms were fundamental to the cubists and many abstract expressionists, and award-winning sculptors have used topology as the basis for their pieces. Dutch artist M.C. Escher represented infinity, Möbius bands, tessellations, deformations, reflections, Platonic solids, spirals, symmetry, and the hyperbolic plane in his works.
"Mathematicians and artists continue to create stunning works in all media and to explore the visualization of mathematics--origami, computer-generated landscapes, tesselations, fractals, anamorphic art, and more."
