What is SVG primarily used for?

SVG, or Scalable Vector Graphics, is primarily used as an XML-based vector image format for two-dimensional graphics. This means it allows for the creation of graphics that can be scaled to any size without losing image quality, which is a significant advantage over raster formats that can pixelate when enlarged. The XML-based structure of SVG allows it to be both human-readable and accessible for machines, enabling easy manipulation and integration into web pages.

SVG is widely utilized for web graphics, including icons, logos, and illustrations, as it supports interactivity and animation. This capability comes from its integration with CSS and JavaScript, which enhances its functionality and aesthetic possibilities on digital platforms. Other formats mentioned in the incorrect options do not offer the same benefits that SVG provides for two-dimensional graphic representation and scalability, making SVG uniquely suited for this purpose.
