This code can produce 2 kinds of suspicious behavior:[[BR]]

1)If I output only single point(a), it's coordinates are invalid(svg output fragment: ''circle cx=""-2147483648"" cy=""-2147483648""'').[[BR]]
 
2)If I add polygon to the output(a and b), I get more relevant output, but still invalid(svg output fragment: ''circle cx=""1000"" cy=""0""'').
