title: How can I calculate the area of a bezier curve?
body: <p>Given the following path (for example) which describes a SVG cubic bezier curve: "M300,140C300,40,500,40,500,140",
  and assuming a straight line connecting the end points 300,140 to 500,140 (closing the area under the curve), is it possible to calculate the area so enclosed?</p>
  
  <p>Can anyone suggest a formula (or JavaScript) to accomplish this?</p>
