prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  template-solid-ts
   +--public
   `--src
       `--assets
  ```
  
  Convert this description:
  
  v1 is a origin directory that bundles 6 subdirectories. Notable ones include app, format, key among others.
  
  The project source code seems to be organized in the 'app' folder.
  
  Let me break down the architecture for you:
  
  At the top level, The 'app' storage space stands empty.
  At the top level, Inside 'format', you'll find it contains no subdirectories.
  In the root directory, 'key' is barren.
  In the root directory, 'layout' features 1 contained folders: compound.
  At level 2, in directory path 'layout / compound', 'compound' contains nothing at present.
  Back to the top level.
  At the top level, 'view' is unpopulated.
  At the main level, 'viewmodel' encapsulates 1 subdirectories: testdata.
  At level 2, in directory path 'viewmodel > testdata', Inside 'testdata', you'll find it is empty.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
