```ruby
module Sodium
  class TagCloud < Node
    attr_accessor :tags

    def initialize
      tags = {}
    end

    def add_tag
      tag
    end
  end
end```

Tag cloud does not need an add_tag method as it extends the DSL
user
```ruby
module Sodium
  class TagCloud < Node
    attr_accessor :tags
    def initialize
      tags = {}
      super
    end
  end
end```
