基于Web的2D繪圖：Two.js

Two.js是一個面向現代瀏覽器的2D繪圖API。對于不同的瀏覽器渲染引擎(svg, canvas, 和webgl)，提供了相同的繪制API。

用法：

// Make an instance of two and place it on the page.
var elem = document.getElementById('draw-shapes').children[0];
var params = { width: 285, height: 200 };
var two = new Two(params).appendTo(elem);

// two has convenience methods to create shapes.
var circle = two.makeCircle(72, 100, 50);
var rect = two.makeRectangle(213, 100, 100, 100);
// The object returned has many stylable properties:
circle.fill = '#FF8000';
circle.stroke = 'orangered'; // Accepts all valid css color
circle.linewidth = 5;
rect.fill = 'rgb(0, 200, 255)';
rect.opacity = 0.75;
rect.noStroke();</pre>
