SVG allows for scalable vector graphics on the web. It uses XML to define vector shapes and graphics that can be scaled or resized without loss of quality. SVG graphics can be created and edited with any text editor, searched, indexed, scripted, and compressed. They are also scalable, zoomable, and can be printed at high resolution. In HTML5, SVG elements can be directly embedded into web pages using SVG tags. SVG is XML-based so each element is available in the SVG DOM and can have JavaScript event handlers attached.

- 3. SVG stands for Scalable Vector Graphics SVG is used to define vector-based graphics for the Web SVG defines the graphics in XML format SVG graphics do NOT lose any quality if they are zoomed or resized Every element and every attribute in SVG files can be animated SVG is a W3C recommendation
- 4. Advantages of using SVG over other image formats (like JPEG and GIF) are: SVG images can be created and edited with any text editor SVG images can be searched, indexed, scripted, and compressed SVG images are scalable SVG images can be printed with high quality at any resolution SVG images are zoom able (and the image can be zoomed without degradation)
- 5. In HTML5, you can embed SVG elements directly into your HTML page: <svg width="300" height="200"> <polygon points="100,10 40,180 190,60 10,60 160,180" style="fill:lime;stroke:purple;stroke-width:5;fillrule:evenodd;" /> </svg>
- 6. SVG is a language for describing 2D graphics in XML. Canvas draws 2D graphics, on the fly (with a JavaScript). SVG is XML based, which means that every element is available within the SVG DOM. You can attach JavaScript event handlers for an element. In SVG, each drawn shape is remembered as an object. If attributes of an SVG object are changed, the browser can automatically re-render the shape. Canvas is rendered pixel by pixel. In canvas, once the graphic is drawn, it is forgotten by the browser. If its position should be changed, the entire scene needs to be redrawn, including any objects that might have been covered by the graphic.
