Final answer:
A digital representation of non-text information like a drawing, chart, or photo is most generally referred to as an image.
Step-by-step explanation:
A digital representation of non-text information such as a drawing, chart, or photo can be referred to by multiple terms depending on the context. However, the most general term for this is an image. This includes various forms like photographs (drawing with light), graphics, and even logographic items which use pictures or symbols to convey a word or idea. Unlike traditional text, images present information simultaneously, allowing for information to be absorbed at a glance but may also possess nuanced details that require closer scrutiny to fully understand. This is especially true for instructional materials, such as in an infographic, where images are combined with text to succinctly convey information.
