The GEC is shown on the wrong side of the clamp.
And while were on a roll the arrow is pointing to the GEC not the electrode.
Correct. Impalement hazard!
New attic insulation graphic. The intent of this graphic is to only show the relative difference in some common attic insulation thickness based on R-38.
(I know there are many combinations and ranges for different climate zones.)

Again the conductor is on the wrong side of the clamp and the rod is not flush or below grade.

Back to the panel illustration, it could be improved by showing the grounded conductor attached to the opposite bus bar and show a green bonding screw to indicate bonding with the grounded bus. Just a thought.
And make the neutral white.
