Image showing "jumping around" required

[radar]

In Ch10, there's this:

<p>
  Both Elixir and our brains need to interpret what's inside the brackets of
  <code>List.first/1</code> first, then interpret <code>List.first/1</code>.
  That requires us to jump around a little in the code because the code is
  not executed in the order that you would read it.
</p>

But I think having an image alongside that explanation would be helpful.
