Much like a planogram indicates where the placements of retail products should be:
plan·o·gram ˈplanəˌɡram/ noun a diagram or model that indicates the placement of retail products on shelves in order to maximize sales.
The link above shows a diagram of clothing arrangements on a wall. Instead of products, think video feed sources.
Could the same word be used to indicate the placement of video feeds on a video wall?
For example, security desk video screens are divided up into however many video feeds exist, and can be resized, or placed in a customized arrangement.
Planogram as well?
