    You can use includegraphics to include the drawing above in your paper or book. It is ok. Jun 9, 2022 at 16:48

    This is very similar to your earlier question from a couple of months ago: tex.stackexchange.com/q/641828/15036 Could you adapt the code from that one?

  • Suggestion: Take a few days to go through and try the minimal introduction on ctan.org/pkg/pgf?lang=en ; then spend some time on details you need in the big manual. // You may want to check for \node, \draw , rounded corners, double distance (graphic parameters) to obtain 80-90 % of said sketch.

Change the value 2 in \resizebox{2\textwidth}{!}{...} to automatically resize the diagram.

output

\documentclass[border=3.14mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{automata, arrows.meta, positioning, shapes}
 
\begin{document}
\resizebox{2\textwidth}{!}{
\begin{tikzpicture}[
>={Stealth[round]},
line width=0.8pt, % make all arrow thicker
state/.style={draw,rounded rectangle,line width=0.4pt},%the state style which has the line width as normal
]

    \node [state, initial, initial text = {I}] (q0) at (0, 0) {$\lbrace q_1,q_2,q_3,q_4,q_8,q_{14} \rbrace$};

    \node [state, right=2cm of q1] (q2){$\lbrace q_{11},q_{12} \rbrace$};
    % Middle row
    \node [state, accepting,xshift=0.5cm, below=2cm of q0] (q3){$\lbrace q_2,q_3,q_4,q_7,q_8,q_{14} \rbrace$};

  • Thank you. How can i make the edges curve in a rounded way instead of forming a right angle?

    @B612, I have updated the answer. Add rounded corners to the `\draw[...]' commands. I also changed one of the coordinates to keep everything aligned. Jun 10, 2022 at 16:12
  • +1 for this very nice job, despite the fact that OP has already asked many times others to do the job for him and didn't even bother to accept answers.
