<canvas id="canvas"></canvas>

JavaScript

The first line begins at (50, 50) and ends at (200, 50). The second line begins at (50, 90) and ends at (280, 120).

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

ctx.beginPath();
ctx.moveTo(50, 50);   // Begin first sub-path
ctx.lineTo(200, 50);
ctx.moveTo(50, 90);   // Begin second sub-path
ctx.lineTo(280, 120);
ctx.stroke();
