//Change Text color
doc.setTextColor(150);

//Adding a page
doc.addPage();

//Adding a Line
doc.setLineWidth(0.5);
doc.line(X1, Y1, X2, Y2); // horizontal line

//Draw Rectangle
doc.setDrawColor(0);
doc.setFillColor(255,0,0);
doc.rect(X1, Y1, WIDTH, HEIGHT, 'F');  //F is for Fill
doc.rect(X1, Y1, WIDTH, HEIGHT, 'D');  //D is for Draw
doc.rect(X1, Y1, WIDTH, HEIGTH, 'FD');  //FD is for Fill and Draw 

//Draw Triangle
doc.setLineWidth(1);
doc.setDrawColor(255,0,0);

2).Download the generated PDF File

JSPDF lib generates pdf at the browser and provides an option(using data-uri) to download. But it is not working all browsers.
You can download the generated PDF using Downloadify plugin.
Downloadify plugin provides an option to download any file(not only pdf) generated at browser.

	
//'downloadify' is the div id
//'Simple.pdf' is the output file.
Downloadify.create('downloadify',{
			filename: 'Simple.pdf',
			data: function()
			{ 
					var doc = new jsPDF();
					doc.setFontSize(22);
					doc.text(20, 20, 'FirstPage: My First PDF');
					doc.addPage();
					doc.setFontSize(16);
					doc.text(20, 30, 'Second Page This is some normal sized text underneath.');	
				return doc.output();
			},
			onComplete: function(){ alert('Your File Has Been Saved!'); },
			onCancel: function(){ alert('You have cancelled the saving of this file.'); },
			onError: function(){ alert('You must put something in the File Contents or there will be nothing to save!'); },
			downloadImage: 'images/download.png',
			swf: 'images/downloadify.swf',
			width: 100,
			height: 30,
			transparent: true,
			append: false
		});
