HTML5 & Canvas

Added in HTML5, the HTML <canvas> element can be used to draw graphics via scripting in JavaScript (MDN)

<canvas id="a" width="300" height="225"></canvas> 
var b_canvas = document.getElementById("b");
var b_context = b_canvas.getContext("2d");
b_context.fillRect(50, 25, 150, 100);
context.beginPath();
context.moveTo(0, 40);
context.lineTo(240, 40);
context.moveTo(260, 40);
context.lineTo(500, 40);
context.moveTo(495, 35);
context.lineTo(500, 40);
context.lineTo(495, 45);

HTML5 sVG

Scalable Vector Graphics (SVG) is an XML markup language for describing two-dimensional vector graphics. SVG is essentially to graphics what XHTML is to text.

 <svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     version="1.1"
     baseProfile="full">
  <g fill-opacity="0.7" stroke="black" stroke-width="0.1cm">
    <circle cx="6cm" cy="2cm" r="100" fill="red"
                    transform="translate(0,50)" />
    <circle cx="6cm" cy="2cm" r="100" fill="blue"
                    transform="translate(70,150)" />
    <circle cx="6cm" cy="2cm" r="100" fill="green"
                    transform="translate(-70,150)" />
  </g>
</svg>
