Wavy lines are curved lines that move in a smooth, undulating manner. They can be found in various forms of art, design, and nature, creating a sense of movement and fluidity. Wavy lines can vary in width and length, and they often evoke feelings of calmness or playfulness. In graphic design, wavy lines are used to add visual interest and can guide the viewer's eye across a composition. They are also commonly seen in patterns, textiles, and even in the natural world, such as the gentle ripples of water or the contours of hills.
