prompt: Your task is to convert the following English description into an ASCII tree format.
  
  circl is a source directory that gathers 5 subdirectories. Notable ones include dh, ecc, internal among others.
  
  Let me break down the construction for you:
  
  At the main level, 'dh' shelters 2 subdirectory elements: x25519, x448.
  At level 2, in directory path 'dh / x25519', The 'x25519' folder has no content.
  Within directory hierarchy 'dh > x448', Inside 'x448', you'll find it appears to be unused.
  At the main level, 'ecc' maintains 1 subfolders: goldilocks.
  At level 2, in directory path 'ecc > goldilocks', Inside 'goldilocks', you'll find it is barren.
  Back to the top level.
  At the main level, 'internal' hosts 2 child directories: conv, sha3.
  In nested path 'internal > conv', The 'conv' compartment contains no subdirectories.
  At level 2, in directory path 'internal > sha3', The 'sha3' container has no content.
  At the main level, 'math' incorporates 3 child directories: fp25519, fp448, mlsbset.
  In nested path 'math > fp25519', 'fp25519' has no content.
  Within directory hierarchy 'math > fp448', The 'fp448' container is barren.
  In nested path 'math / mlsbset', 'mlsbset' holds no subdirectories at the moment.
  At the top level, 'sign' organizes 2 child directories: ed25519, ed448.
  In nested path 'sign > ed25519', 'ed25519' is barren.
  Within directory hierarchy 'sign > ed448', The 'ed448' storage space is a vacant space.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  node_modules
   +--@somenamespace
   |   `--eslint-formatter-foo
   `--eslint-formatter-bar
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
