Vector graphics are images created using mathematical equations to define shapes, lines, and colors. Unlike raster graphics, which are made up of pixels, vector graphics can be scaled infinitely without losing quality, making them ideal for logos and illustrations that require resizing. Commonly used in graphic design, vector graphics are created with software like Adobe Illustrator or CorelDRAW. They are favored for their versatility and clarity, allowing designers to produce crisp images that maintain their integrity across various formats and sizes.
