prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  export-default
   +--__snapshots__
   +--escaped
   |   `--__snapshots__
   `--export-default-from
       `--__snapshots__
  ```
  
  Convert this description:
  
  source-and-transformers-child-nodes is a base directory that collects 6 subdirectories. Notable ones include source-added, source-changed, source-removed among others.
  
  Let me break down the system for you:
  
  At the top level, 'source-added' has 2 contained folders: gatsby-source, gatsby-transformer.
  Within directory hierarchy 'source-added > gatsby-source', The 'gatsby-source' data structure is unpopulated.
  Within directory hierarchy 'source-added → gatsby-transformer', The 'gatsby-transformer' collection is unpopulated.
  Back to the top level.
  At the main level, 'source-changed' comprises 2 subdirectories: gatsby-source, gatsby-transformer.
  In nested path 'source-changed → gatsby-source', The 'gatsby-source' repository is barren.
  At level 2, in directory path 'source-changed → gatsby-transformer', Inside 'gatsby-transformer', you'll find it is unpopulated.
  Back to the top level.
  At the main level, 'source-removed' hosts 2 subfolders: gatsby-source, gatsby-transformer.
  In nested path 'source-removed → gatsby-source', 'gatsby-source' sits empty.
  In nested path 'source-removed / gatsby-transformer', Inside 'gatsby-transformer', you'll find it is an empty container.
  At the main level, 'transformer-added' retains 2 subfolders: gatsby-source, gatsby-transformer.
  Within directory hierarchy 'transformer-added > gatsby-source', The 'gatsby-source' repository sits empty.
  At level 2, in directory path 'transformer-added / gatsby-transformer', Inside 'gatsby-transformer', you'll find it lacks any subdirectories.
  In the root directory, 'transformer-changed' incorporates 2 folders: gatsby-source, gatsby-transformer.
  Within directory hierarchy 'transformer-changed / gatsby-source', The 'gatsby-source' directory has yet to be populated.
  In nested path 'transformer-changed / gatsby-transformer', Inside 'gatsby-transformer', you'll find it is vacant.
  Back to the top level.
  In the root directory, 'transformer-removed' bundles 2 directories: gatsby-source, gatsby-transformer.
  Within directory hierarchy 'transformer-removed > gatsby-source', 'gatsby-source' has nothing inside.
  In nested path 'transformer-removed → gatsby-transformer', 'gatsby-transformer' has yet to be populated.
  Back to the top level.
