CCNA, CCNP, MCSA, CCNA Final Exam, All Answer Test Module With 100/100

I'm using the gRaphael JavaScript library, and am attempting to draw a simple line graph. The code I currently have on the page is: <script language="javascript" type="text/javascript"> var paper = Raphael(10, 50, 640, 480); paper.g.linechart(10,10,300,220,[1,2,3,4,5],[10,20,15,35,30]); </script> I found this code from a tutorial, located here: https://github.com/kennyshen/g.raphael/blob/master/examples/linechart/linechart_basic.html All the required files, raphael.js , g.raphael.js , and g.line.js , are included earlier on the page as well. When I view the page, it just shows up as a white screen. Would appreciate any help, thank you.
