  We clarify steps for determining the ${\rm SL}(2,\mathbb{C})$-character
variety of any arborescent knot.
  Interestingly, we show that the `excellent parts' of arborescent knots
$K_1,K_2$ are isomorphic if $K_1$ can be related to $K_2$ through certain moves
on projection diagrams.
  Furthermore, we give a sufficient condition in terms of diagram for the
existence of components of dimension larger than $1$. A generalization to
arborescent links is sketched.
