prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  request
   +--examples
   +--lib
   `--tests
       +--browser
       |   `--ssl
       +--fixtures
       `--ssl
           `--ca
  ```
  
  Convert this description:
  
  _expected is a source directory that holds 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the framework for you:
  
  At the main level, 'amd' possesses 1 directories: chunks.
  Within directory hierarchy 'amd > chunks', The 'chunks' container has no content.
  Back to the top level.
  At the main level, 'cjs' keeps 1 subdirectory elements: chunks.
  Within directory hierarchy 'cjs → chunks', 'chunks' contains no subdirectories.
  Back to the top level.
  At the main level, 'es' holds 1 folders: chunks.
  Within directory hierarchy 'es / chunks', 'chunks' has yet to be populated.
  Back to the top level.
  In the root directory, 'system' bundles 1 nested folders: chunks.
  At level 2, in directory path 'system / chunks', The 'chunks' compartment awaits content.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
