prompt: Your task is to convert the following English description into an ASCII tree format.
  
  mobx is a root directory that holds 4 subdirectories. Notable ones include __tests__, flow-typed, scripts among others.
  
  The project source code seems to be organized in the 'src' section.
  
  Let me break down the design for you:
  
  At the main level, '__tests__' organizes tests across 5 separate folders.
  In nested path '__tests__ / decorators_20223', Inside 'decorators_20223', you'll find it has been left empty.
  In nested path '__tests__ / mixed-versions', The 'mixed-versions' collection is vacant.
  At level 2, in directory path '__tests__ / perf', Inside 'perf', you'll find it appears to be unused.
  At level 2, in directory path '__tests__ / v4', 'v4' incorporates 1 subfolders: base.
  At level 3, in directory path '__tests__ / v4 / base', 'base' contains 1 directory entries: __snapshots__.
  At level 4, in directory path '__tests__ > v4 > base > __snapshots__', The '__snapshots__' folder is barren.
  In nested path '__tests__ → v5', 'v5' groups 3 child directories: base, flow, utils.
  In nested path '__tests__ → v5 → base', 'base' houses 1 child directories: __snapshots__.
  At level 4, in directory path '__tests__ → v5 → base → __snapshots__', '__snapshots__' contains no subdirectories.
  In nested path '__tests__ → v5 → flow', Inside 'flow', you'll find it has no content.
  At level 3, in directory path '__tests__ → v5 → utils', The 'utils' container has no folders inside.
  Back to the top level.
  At the top level, The 'flow-typed' data structure hasn't been filled with any content.
  At the top level, Inside 'scripts', you'll find it has yet to be populated.
  At the top level, The 'src' directory carries 4 folders for code organization.
  Within directory hierarchy 'src → api', 'api' holds no subdirectories at the moment.
  Within directory hierarchy 'src > core', The 'core' container is unpopulated.
  At level 2, in directory path 'src > types', The 'types' container has no folders inside.
  At level 2, in directory path 'src > utils', 'utils' is unpopulated.
  
  
  Format your response in this style:
  ```
  api
   +--plugins
   `--tasks
       `--bundling
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
