Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. It defines graphics as shapes, paths, text, and filter effects. For example, an SVG file can define a simple circle using XML code like “, which renders a red circle with a black border.
The importance of vector graphics lies in their scalability without loss of quality; they can be scaled to any size without becoming pixelated, making them ideal for responsive web design, logos, and icons. Historically, the development of vector graphics addressed limitations inherent in raster-based formats, which suffer from quality degradation upon scaling. Its adoption across various platforms and devices has significantly enhanced the visual experience on the web.
