   Assuming you have booted the SVG DOM
(see the Wiki if you don't know

what I mean).  They you can use getBBox on just
about any SVG element


and it will tell you the location of that element
in it's local coordinate

system.  Then it's a trivial matter to calculate

it's geometric center.




   However, this is occasionally not useful
for mapping applications where the

shape of the element may be such that the geometric

center is outside


of the filled region for the shape.  Handling
these cases automatically 

is far from trivial, so I am forced to leave you with
a problem rather 

than a solution.
