SVG stands for Scalable Vector Graphics. SVG is an XML-based vector image format for two dimensional graphics with support for interactivity and animation. Unlike raster image formats (such as JPEG and PNG) that store images as a grid of pixels SVG images are composed of geometric shapes, paths, and text elements that can be scaled, rotated, and animated without loosing quality.

Here are some key characteristics and features of that make SVG unique from raster images and logos:

Scalability:
SVG images are resolution-independent, meaning they can be scaled to any size without loss of quality. Whether you are viewing an SVG image on a small screen or a large display, it will still maintain its clarity and sharpness.

Vector-based:
SVG images are composed of mathematical descriptions of shapes and paths rather than pixels. This makes them light-weight and ideal for graphics that needs to be resized or manipulated programmatically.

Text-based:
SVG images are written in XML format, which is a human readable mark-up language. This makes it easy to create and edit SVG files using text editors of graphics design software.

Interactivity:
SVG support interactivity and scripting through event handlers and DOM manipulation. You can add interactive elements like buttons, links, and animations to SVG graphics using Java script.

Accessibility:
SVG images can include text elements that ae accessible to screen readers and assistive technologies, making them suitable for creating accessible web contents.

Browser Support:
All modern web browser support SVG natively, making it widely compatible format for web development. SVG can be embedded directly into HTML document using <svg> element or referenced externally using <img> or <object> element.

SVG graphics are commonly used for variety of purposes, including logos, icons illustrations, data visualizations, maps and user interfaces. They offer flexibility, performance, and accessibility advantages over raster image formats, making them a popular choice for web and digital design.
