I think you're overlooking some very powerful libraries, however if you're determined to do this yourself you're going to need to use HTML5 and the Canvas object. Have a look at this great tutorial to get you started. Here's a snapshot of what you'll need to get to grips with:

$(document).ready(function() {

    var graph = $('#graph'),

        c = graph[0].getContext('2d');



    c.lineWidth = 2;

    c.strokeStyle = '#333';

    c.font = 'italic 8pt sans-serif';

    c.textAlign = center;



    c.beginPath();

    c.moveTo(xPadding, 0);

    c.lineTo(xPadding, graph.height() - yPadding);

    c.lineTo(graph.width(), graph.height() - yPadding);

    c.stroke();

});
