[D3] Why must .append() come before .text()?

Tell us what’s happening:

Why must .append() come before .text() in order to render in the following block of code? I’m trying to dig into the documentation but am having a hard time understanding what is happening conceptually.

  const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];

  // Add your code below this line
    .text('New Item')
  // Add your code above this line

If I had to take a stab at it I would guess it is because .text([text]).append('h2') would try to append the h2 elements to text nodes(?) which I would presume is impossible. Please help me understand.

Documentation for reference:
Append and Text.

Yes, that’s correct, it wouldn’t make any sense.

Glad to know, thanks!
