Wave Pattern Graph Illustration

A simple graphical representation featuring a continuous blue line forming three distinct, upward-curving arches on a dark background. The pattern is overlaid on a subtle gray grid, suggesting a mathematical or scientific illustration of a periodic wave or signal, potentially depicting a rectified alternating current or a similar oscillating phenomenon. It visually conveys the concept of wave amplitude and periodicity.
