What is the primary focus of vector drawing?

The primary focus of vector drawing is indeed the use of mathematical equations to create shapes. Vector graphics are created using points, lines, curves, and shapes based on mathematical expressions, which allows for scalability without loss of quality. This means that no matter how much a vector image is enlarged or reduced, it retains its sharpness and clarity. Unlike pixel-based images, which become blurry when scaled, vector graphics maintain their resolution, making them ideal for logos, illustrations, and any design work that requires resizing. This mathematical basis allows artists and designers to create precise and clean images that can be easily manipulated and edited.

While the other options refer to different aspects of graphic design, they do not capture the essence of vector drawing. Pixel-based image manipulation involves raster graphics, photographic elements pertain to digital photography or photomontage, and decorative arts are more related to aesthetic design rather than the technical creation of images through mathematical constructs.
