How to draw a graph in LaTeX?

Question

First of all, let me say that I am using LyX, although I have no problem using ERT.

Secondly, what is the easiest way to make a simple graph like this in Latex?

I saw some documents with graphs, and I saw some examples, but I could not understand how easy it was to draw a simple graph - which packages I needed, etc.

Answer 1

TikZ can do this.

Quick demo:

\documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} [scale=.8,auto=left,every node/.style={circle,fill=blue!20}] \node (n6) at (1,10) {6}; \node (n4) at (4,8) {4}; \node (n5) at (8,9) {5}; \node (n1) at (11,8) {1}; \node (n2) at (9,6) {2}; \node (n3) at (5,5) {3}; \foreach \from/\to in {n6/n4,n4/n5,n5/n1,n1/n2,n2/n5,n2/n3,n3/n4} \draw (\from) -- (\to); \end{tikzpicture} \end{document} 

gives:

Additional information on TikZ: http://sourceforge.net/projects/pgf/ , where I assume that an installation guide will also be present.

Answer 2

Perhaps use tikz .

Answer 3

Besides the (excellent) suggestion to use TikZ, you can use gastex . I used this before TikZ was available, and it was doing its job too.

Answer 4

I used Graphviz ( https://www.graphviz.org/gallery ) along with latex, using the dot command to create graphics in PDF and includegraphics to include them.

If graphviz produces what you aim for, this might be the best way to integrate: dot2tex: https://ctan.org/pkg/dot2tex?lang=en

Answer 5

In my experience, I always use an external program to generate a graph (math, gnuplot, matlab, etc.) and export the graph in pdf or eps format. Then I include it in the document with includegraphics .
