SVG (Scalable Vector Graphics) is an XML-based vector image format used for describing two-dimensional graphics. Unlike raster image formats like JPEG or PNG, which store images as a grid of pixels, SVG images are defined using mathematical equations and geometric shapes, making them resolution-independent and suitable for scaling to any size without losing quality.
SVG images can be created and edited using various tools such as Adobe Illustrator, Inkscape, or even plain text editors. They can include shapes like lines, circles, rectangles, and polygons, as well as text and gradients. Additionally, SVG supports advanced features like animations, interactivity, and filters, making it suitable for creating dynamic and engaging visual content on the web.
One of the key advantages of SVG is its compatibility with other web technologies. SVG images can be embedded directly into HTML documents using the `<svg>` element or included as external files, and they can be styled and manipulated using CSS and JavaScript. This allows for seamless integration of vector graphics into web pages and applications, enhancing user experience and accessibility.
For example, here’s a simple SVG code to draw a red circle:
<svg width=”100″ height=”100″>
<circle cx=”50″ cy=”50″ r=”40″ fill=”red” />
</svg>
In this example, the `<svg>` element defines the SVG canvas with a width and height of 100 units, and the `<circle>` element draws a red circle with a center at (50,50) and a radius of 40 units. This SVG image can be displayed in any web browser and scaled without loss of quality.
