Answer from AI

Vector graphics (SVG) describe images using mathematical formulas — lines, curves, polygons. This allows scaling the image without loss of quality, as it is redrawn at any size.

Raster graphics consist of pixels — small dots with fixed colors. When scaling a raster image, the quality deteriorates, resulting in pixelation and blurring.

In web development, SVG is used for icons, logos, diagrams, and animations where clarity at any resolution is important. SVG can be embedded directly into HTML as a <svg> tag, styled with CSS, and controlled via JavaScript, making it very flexible for interactive and responsive interfaces.

Example of embedding SVG in HTML:

<svg width="100" height="100" viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg">
  <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
</svg>
