"The line" style refers to a form of minimalist art where the image is created using a continuous line that never intersects. The artwork features a single, unbroken line that outlines shapes and forms, and can range from abstract to representational. This style emphasizes simplicity, fluidity, and the use of negative space to suggest rather than depict detail. It's a study in constraint and the power of a single line to convey an entire scene or subject.
