  Convert this description:
  
  chunk-graph is a origin directory that bundles 4 subdirectories. Notable ones include issue-15173, issue-17989, issue-9634 among others.
  
  Let me break down the construction for you:
  
  In the root directory, 'issue-15173' stores 6 several directories.
  At level 2, in directory path 'issue-15173 / commonAsync', 'commonAsync' has been left empty.
  Within directory hierarchy 'issue-15173 / commonSync', Inside 'commonSync', you'll find it has no content.
  In nested path 'issue-15173 → entries', Inside 'entries', you'll find it has been left empty.
  In nested path 'issue-15173 / featureA', The 'featureA' section awaits content.
  In nested path 'issue-15173 → featureB', 'featureB' has no content.
  Within directory hierarchy 'issue-15173 / featureC', The 'featureC' folder is vacant.
  Back to the top level.
  At the main level, Inside 'issue-17989', you'll find it hasn't been filled with any content.
  In the root directory, The 'issue-9634' storage space is barren.
  At the main level, Inside 'rewalk-chunk', you'll find it contains nothing at present.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
