  "description": "The eleven roles a node may take, each drawn as the bundled default theme draws it: start and terminal are pills, with the terminal in a heavier line; a step is a plain rectangle; a decision is a diamond; emphasis is a rectangle at the heavier weight; a note has no outline at all; a group is a dashed rectangle; and the three flowchart symbols are a parallelogram for data in or out, a box with doubled sides for a process defined elsewhere, and a drum for where data rests; a person — a body under a round head — is a human, as against a system. An author names the role and the theme decides the shape, so a different theme draws this same document differently.",
  "caption": "Say what the box is, not what it looks like — the shape follows.",
