Graphs in TeX or LaTeX [duplicate]

This question already has an answer here:

Is it possible to draw graphs like the image below in LaTeX? marked as duplicate by Henri Menke, ChrisS, Troy, cfr, Stefan PinnowSep 2 '17 at 5:23

• Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – CarLaTeX May 1 '17 at 10:15
• Welcome to TeX.SX! Please add alwasy a minimal working example (MWE), that illustrates your problem. Starting with \documentclass and ending with \end{document}. – Bobyandbob May 1 '17 at 10:30
• I think this post: tex.stackexchange.com/q/15779/101651 could be useful for you if you would like to learn tikz. – CarLaTeX May 1 '17 at 17:41

Another Tikz solution.

\documentclass[border=5mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc,positioning}
\begin{document}
\begin{tikzpicture}[
State/.style={inner sep=0pt,outer sep=0pt,minimum size=2mm,fill=black,circle},
node distance=2cm and 1cm
]
\node[State,label=180:V5] (V5) at (0,0){};
\node[State,label=180:V1,above=of V5] (V1){};
\node[State,label=-90:V4,right=of V5] (V4){};
\coordinate[right=of V4](V2base);%% Halfway between V4 and V3
\node[State,label=0:V3,right=of V2base] (V3){};
\node[State,label=90:V2] (V2) at (V2base |- V1){};
\node[State,label=180:V6] (V6) at ({$(V5)!0.5!(V4)$} |- {$(V5)!0.5!(V1)$}){};
\draw (V1)--(V2)--(V3)--(V4)--(V5) (V4)--(V2);
\end{tikzpicture}

\end{document} You can do it with pstricks. You can compile with pdflatex launching the compiler with the --enable-write18 switch (MiKTeX) or -shell-escape (TeX Live, Mac TeX). Alternativeli, remove auto-pst-pdf loading and compile via latex + dvips + pstopdf or via xelatex.

\documentclass[border=3pt]{standalone}
\usepackage{pst-node, auto-pst-pdf}

\begin{document}

\psset{colsep=1.5cm, rowsep=2cm, dotsize=6pt, labelsep=2pt}%
\sffamily
\begin{psmatrix}
%%% Matrix nodes
\dotnode{1} & & \dotnode{2} \\
\dotnode{5} & \dotnode{4} & &\dotnode{3}
%%% Connections
\ncline{1}{2}\ncline{2}{3}\ncline{3}{4}\ncline{4}{5}\ncline{2}{4}
\ncline[linestyle=none]{1}{4}\ncput{\dotnode{6}}
\nput{180}{1}{V1}\nput{90}{2}{V2}\nput{0}{3}{V3}
\nput{-120}{4}{V4}\nput{180}{5}{V5}\nput{180}{6}{V6}
\end{psmatrix}

\end{document} Do we want to miss a solution with a tikz matrix? Of course not!

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}
\tikzset{%
mypoint/.style={circle, fill=black},
}

\begin{document}
\begin{tikzpicture}
\matrix[column sep=.5em, row sep=4ex, inner sep=0pt, minimum width=6pt] (M) {%
\node[mypoint, label={[left,xshift=-4pt]V1}] (V1) {}; & & & & & \node[mypoint, label={above:V2}] (V2) {}; \\
& \node[mypoint, label={left:V6}] (V6) {}; \\
\node[mypoint, label={[left,xshift=-4pt]V5}] (V5) {}; & & \node[mypoint, label={below left:V4}] (V4) {}; & & & & & & \node[mypoint, label={[right,xshift=2pt]V3}] (V3) {};\\
};
\draw (V1) -- (V2);
\draw (V5) -- (V4) -- (V3);
\draw (V4) -- (V2);
\draw (V2) -- (V3);
\end{tikzpicture}
\end{document} • I like your coding @CarLaTeX – Biki Teron May 2 '17 at 2:57
• i like your code and i understand it but i can ask you what about draw self loop by using your code or can you help my to graph – Maryam Fasfous May 2 '17 at 6:04
• @MaryamFasfous The \matrix is more or less like a tabular. Did you read the post linked to my comment to your question? To learn tikz I suggest to you to read the tutorial at the beginning of the TikZ & PGF manual. If you have other questions, don't hesitate to post them! – CarLaTeX May 2 '17 at 6:08
• thak you very much but can you but link in comment here – Maryam Fasfous May 2 '17 at 6:23
