Stick your data below. Expected in either the CSV format (each line carrying a pair of parent,child or child,parent; check the right button below) or JSON (each key being a parent and corresponding value an array of children {parent: [child, child, ...], parent: [...]}, or a child and corresponding value an array of parents {child: [parent, parent, ...], child: [...]}).

Keep it consistent, no mixing between these formats.

The resulting DOT code will be dumped to the console.

You have to keep it reasonable in term of number of objects (aka nodes) involved or the diagram will be unreadable.
