How can I transform a handwritten graph image into a tikzpicture LaTeX code?

Question

I have for example a handwritten graph:

I am looking for a website (or alternative solution) like Mathpix, which transforms my handwritten graph into a tikzpicture code. So that my output looks like followed:

\begin{tikzpicture}[thick, auto, scale=0.8, transform shape]
    \node [state] (v0) {$v_0$};
    \node [state, above right=of v0] (v1) {$v_1$};    
    \node [state, below right=of v0] (v2) {$v_2$};    
    \node [state, below=of v0] (v3) {$v_3$};
    \node [state, below=of v3] (v4) {$v_4$};
    \node [state, below right=of v3] (v5) {$v_5$};
    \node [state, below right =of v4] (v6) {$v_6$};
    \path
    (v0) edge[-] node {} (v1);
    \path
    (v0) edge[-] node {} (v2);
    \path
    (v0) edge[-] node {} (v5);
    \path
    (v3) edge[-] node {} (v6);
    \path
    (v4) edge[-] node {} (v2);
    \path
    (v4) edge[-] node {} (v6);
\end{tikzpicture}

(i) please extend your code fragment to complete small document, (ii) how your diagram should like? As is shown on image? If not, please provide the sketch of desired result. — Zarko, Dec 30 '22 at 14:22
Does this answer your question? Sketching free-hand, importing into TikZ — user202729, Mar 19 '24 at 02:33

This one seems to have better answers than the duplicate, maybe reverse the closure (i.e., close the other question as a duplicate of this one). — Marijn, Mar 19 '24 at 15:34
@Marijn What a mess. (but there are some possibly useful answers in the other one too, and that one has more votes overall so... maybe a reasonable option is just to repost useful answers on the other question as community wiki) — user202729, Mar 20 '24 at 21:16

Here is a website which can help you draw almost anything.

It does not automatically transform your hand drawn image, it only reduces the effort you need to achieve the desired result.

yEd is a general-purpose graph editor that can import a variety of file formats, including images of hand-drawn graphs. It has a feature to export the graph as TikZ code, which you can then include in your LaTeX document. While it is not able to perfectly recreate the hand-drawn graph, it can save you a significant amount of time and effort compared to manually recreating the graph in TikZ.

FreeTikz is a web-based tool to convert hand-drawn diagrams into tikz code. Click here to run.

+1: Is \usepackage{freetikz} part of CTAN? I seem not to be able to find it. – Dr. Manuel Kuehner Jan 04 '23 at 22:13

If you click on the link you can download the freetikz.sty from the webpage – John Smith Jan 04 '23 at 22:16
Ah, I should have been investigating more thoroughly – Dr. Manuel Kuehner Jan 04 '23 at 22:22
@JohnSmith I don't see where. But tikz seems to compile correctly. And the only thing that seems to be done is transform handwritten into tikz picture. – youthdoo Jan 05 '23 at 01:21
