Why the difference between canvas and svg?

Answer 1

Canvas is pixel based. Has worse quality, but is faster and better for gaming and such. As SVG is vector-based, better image quality, heavier, and better for applications.

Answer 2

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.

Answer 3

in SVG you can play with the width and height as you want without any change in the quality that's what's mean not pixel-based.not as canvas it's pixel-based.but SVG has more accesibility and canvas is more fast.
