What term is used to describe an outline or plan of a work of art?

The term that best describes an outline or plan of a work of art is "Design." In the context of art and visual projects, design encompasses the overall conceptual framework and intentional arrangement of elements within a piece, whether it is a painting, sculpture, animated sequence, or any other form of artistic expression. It involves thoughtful consideration of composition, color, form, and function to convey a particular message or aesthetic.

While "sketch," "blueprint," and "framework" may relate to planning in specific contexts, they do not capture the comprehensive nature of design. A sketch is often a rough drawing that serves as a first step in the design process, rather than a fully developed concept. A blueprint typically refers to a technical drawing intended for construction or engineering purposes, and while it can illustrate a plan, it is not specifically related to artistic endeavors. Framework generally indicates a structure or support but does not directly imply the artistic intentions and decisions involved in the creation process. Therefore, design is the most fitting term for outlining or planning a work of art.
