Copy this link (Ctrl+C). The diagram is stored in the link itself, so it never reaches the server, but anyone with the link can open it.

Start from a template:

Structure

Late deliveries          first line = the problem
People                   no indent = category (bone)
  Drivers untrained      indent = cause
    No onboarding        indent more = sub-cause
# a comment              # lines are ignored

Colors

People [red]             colors the branch and everything under it
  Old trucks [#e65100]   any #hex works too

Names: red, orange, yellow, green, teal, blue, navy, purple, pink, brown, gray, black. You can also click any part of the diagram to pick a color.

Status

  ! Drivers untrained    likely / root cause (bold)
  ~Old trucks~           ruled out (struck through)
@numbering: on           number labels 1, 1.1, 1.1.1…

Or click a cause in the diagram and choose Likely, Ruled out or Normal.

Legend

@legend Color key        starts the legend (title optional)
[green] Items checked    color, then what it means
