Subject: SVG::Graph

Guys I have tried SVG::Graph... my goodness, this is so great.
However I found a couple of strange things in the documentation.

1) The links to the sample are broken (for example: www.germane-
software/repositories/public/SVG/test/single.rb)

2) If I try the example:

  require 'SVG/Graph/Pie'

  fields = %w(Jan Feb Mar)
  data_sales_02 = [12, 45, 21]

  graph = SVG::Graph::Pie.new({
          :height => 500,
    :width  => 300,
    :fields => fields,
  })

  graph.add_data({
          :data => data_sales_02,
    :title => 'Sales 2002',
  })

  print "Content-type: image/svg+xml\r\n\r\n"
  print graph.burn();


in this way: graph.rb > graph.svg
Then I get an error while loading the image at the first line. It 
doesn't like the -print "Content-type: image/svg+xml\r\n\r\n"-. 
Eliminating that line it works like a charm.

Could you please explain me why do I have to eliminate that line to 
make it work?

Thanks,
TKMark
