Introduction
In HTML5 we can draw graphics using HTML elements instead of depending on images or third-party components like Flash.
There are the following two type of graphics elements:
- Canvas
- Scalable Vector Graphics (SVG)
Canvas Element
The <canvas> element:
- helps the browser to draw shapes and images without any plugin.
- is used to draw graphics, on the fly, via scripting.
- has several methods for drawing paths, boxes, circles, characters and adding images.
