About your FFIELD package

Hello.

   I have been very interested in your packages.

   Excellent works!!

  Curently this works fine on my MacBook Pro.

 I'd like to ask you following questions.

 1. Is this package available for map data's attributes text placement using maptools?

2.  Any plan to extend placement with different size of text fonts?

3. Do you know following Dorling's circular cartogram? I think your packges can create  these maps adding some modifications.
