Add hover event on intersecting sections of SVG graph

I have create a fiddle http://jsfiddle.net/bhyt7L5z/

I have 5 ellipse intersecting each other. I want to capture hover event on intersecting areas and show corresponding data in tool-tip. ASomething like :

    $('paths').hover(function(e) {
        console.log('show content related to intersection');
    });

Can anyone give me pointers on how to do this.

Is there any chart available in JavaScript which gives interactive elliptical venn diagram

Regards
