seems different, "X" and "N" are not about image. And what about
"pyramid"? It's about shape or form. But it's a little different.

I think you posted to the wrong group but I would propose
"figurograph" from the Latin roots for shape and writing.
Pictograph or ideogram are the closest existing words in meaning.
Another example word would be "ell".
