  Convert this description:
  
  opengraph is a origin directory that holds 3 subdirectories: article, invalid-image and static.
  At the top level, 'article' is unpopulated.
  At the top level, Inside 'invalid-image', you'll find it has no content.
  At the top level, 'static' groups 1 subdirectories: override.
  At level 2, in directory path 'static / override', The 'override' data structure is barren.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
