I cannot figure out how to scale or rotate an entire automata tikz picture.

Taking an example from page 577 of the manual, my approach clearly is not doing what I want -- to scale and rotate the entire figure. I have moved the scale=..., around within the [] too, but nothing seems to get what I want or expect. Am I (dense and) missing something or is scaling and rotating within automata harder than I thought or impossible? Thanks for any help, dave

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary {arrows.meta,automata,positioning,shadows}

\begin{document}
\begin{tikzpicture}[%
scale=2, rotate= 90, % this line is my addition
shorten >=1pt,node distance=2cm,on grid,>={Stealth[round]},thick,
every state/.style={fill,draw=none,orange,text=white,circular drop shadow},
accepting/.style ={green!50!black,text=white},
initial/.style ={red,text=white}]
\node[state,initial] (q_0) {$q_0$};
\node[state] (q_1) [above right=of q_0] {$q_1$};
\node[state] (q_2) [below right=of q_0] {$q_2$};
\node[state,accepting](q_3) [below right=of q_1] {$q_3$};
\path[->] (q_0) edge node [above left] {0} (q_1)
edge node [below left] {1} (q_2)
(q_1) edge node [above right] {1} (q_3)
edge [loop above] node {0} ()
(q_2) edge node [below right] {0} (q_3)
edge [loop below] node {1} ();
\end{tikzpicture}
\end{document}

You also need `transform shape', i.e.

scale=2, rotate= 90, transform shape, % etc

See section "17.7 Transformations".

Thank you, that works nicely.
