Scalable Vector Graphics (SVG) is an XML-based vector image format for defining two-dimensional graphics, a core technology in modern web development and computer graphics. Unlike raster formats (e.g., JPEG, PNG) which use a fixed grid of pixels, SVG describes images using mathematical constructs like paths, shapes, and text. This fundamental difference allows SVG images to be scaled to any size without any loss of quality or pixelation, making them ideal for responsive design and high-resolution displays. As an open standard, its text-based XML structure means SVGs can be indexed, scripted with JavaScript for interactivity and animation, and styled with CSS, offering a powerful and flexible solution for logos, icons, and complex data visualizations.
