What does "SVG" stand for, and what is its primary use?

The term "SVG" stands for Scalable Vector Graphics, and its primary use is in creating vector images that can be displayed on the web. SVG is a widely accepted format that allows for two-dimensional vector graphics which are defined in a XML text file. This means that SVG images can be scaled to any size without losing quality, making them particularly useful for responsive web design.

Using SVG allows designers to incorporate graphics that look sharp and clear on devices with varying resolutions, such as high-definition screens, without needing to create multiple versions of the same image in different sizes. Furthermore, SVG files are also lightweight and can be easily manipulated with CSS and JavaScript, allowing for interactive and animated graphics on web pages.

The other options do not accurately describe SVG; for instance, referring to it as "Standard Variable Graphics" or attributing uses like raster images or print design misses the key features and advantages that SVG provides specifically for web usage.
