[Stephane Klein]

Hi,

I would like to display a map with Google Maps layer with a circle with 
50km radius.

* In this example http://jsfiddle.net/stephane_klein/VLKzY/2/
I succeed to display a map with circle but I don't know how to calculate 
50km radius. Do you have a tip ?

* No success in this example with Google Maps layer 
http://jsfiddle.net/stephane_klein/JNXQu/1/ Where is my mistake ?

Thanks for your help.

Regards,
Stephane
