# Also requires imagemagick, but the program will yell at you for that.

  ghr.public_gists(count: 100)
end

  @ghr ||= Githubris.new
end

  gists.map(&:files).map(&:values).flatten.map{|f| OpenStruct.new(f) }.map do |f|
    if f.language.nil?
      f.language = "None"

end

Graphene.percentages(files_for(gists), :language).pie_chart('./pie_chart.jpg', 'Languages in the Last 100 Public Gists')
