How to draw the following graph in my manuscript?    I am unable to draw this graph.  Can someone please me to draw this?  I am new to TikZ. I have started learning from this link  but unfortunately it does not show how to draw this kind of graph.  Can someone please help?

I am interested in outputting  this graph in  latex using tikz:    So far I got this:    and my tikz code is   \begin{tikzpicture}     \node[shape=circle,draw=black] (A) at (0,0) {A};     \node[shape=circle,draw=black] (B) at (0,3) {B};     \node[shape=circle,draw=black] (C) at (2.5,4) {C};     \node[shape=circle,draw=black] (D) at (2.5,1) {D};     \node[shape=circle,draw=black] (E) at (2.5,-3) {E};     \node[shape=circle,draw=black] (F) at (5,3) {F} ;      \path [-&gt;] (A) edge node[left] {$5$} (B);     \path [-&gt;](B) edge node[left] {$3$} (C);     \path [-&gt;](A) edge node[left] {$4$} (D);     \path [-&gt;](D) edge node[left] {$3$} (C);     \path [-&gt;](A) edge node[right] {$3$} (E);     \path [-&gt;](D) edge node[left] {$3$} (E);     \path [-&gt;](D) edge node[top] {$3$} (F);     \path [-&gt;](C) edge node[top] {$5$} (F);     \path [-&gt;](E) edge node[right] {$8$} (F);    \end{tikzpicture}   I want to know how to draw the arc between nodes B and E and also thicker  arcs with their lengths in center. Any help is appreciated

I am teaching how to convert from one base to another base, however, I can't find a way to do something like this:    I know little about Tikz, the only thing I have been able to produce is a simple square with a couple of lines over it, so I don't even know where to start. Any suggestions? I don't mind typing all the numbers, what I want to do is to automatize the process of creating the lines.

I'm wondering if it exists a canonical/natural/smooth/economical way of drawing such a diagram    for the definition of a function. The best I managed to do with tikz and align is very poor. I'm a beginner with Latex, hence I apologize in advance in case the question had a trivial answer.

I wish I knew how to draw the this commutative diagram with the TikZ package.    I would also like to know how to put subtitles in the diagram.

Is it possible to load a TikZ library and make it local to a tikzpicture?  I'm writing a long document, and feel like the different TikZ libraries required for different diagrams are "littering" the namespace.

Questions:   Why are the top corners of this number line missing? Why aren't the bottom corners or any other corners of this number line missing? How do I ensure the corners are always there?     \documentclass{article}  \usepackage[left=1.5cm,right=1.5cm,top=2cm,bottom=2cm]{geometry} \usepackage{tikz}   \begin{document}  \begin{tikzpicture}[line width=0.08cm]  \draw (0,0)--(5,0); \draw (0,0.3)--(5,0.3);  \foreach \x in {0,...,5}  {  \node at (\x,-0.55) {\x};  \draw (\x,-0.3)--(\x,0.3);  }  \foreach \x in {0,...,5}  \draw (\x,0)--(\x,0.3);  \end{tikzpicture}  \end{document}   That code yields this:

Is there an easy way to tell if a graph can be embedded on a Möbius strip (with no edges crossing)?  A specific version of this: if a simple graph with an odd number of vertices has all vertices of degree 4, can it be embedded on a Möbius strip?    Answer summary:   There are  for the Möbius strip that are   and drawn on . There are  for the Möbius strip, they are , and even better there are only .   I have not yet answered the second question, but Jim Belk's excellent explanation has given me good ideas.

Look at this image:   This is what I get from this:     \begin{tikzpicture}     \draw[style=help lines] (-5,-5) grid (5,5);     \draw (-4,0)--(4,0);     \draw (0,-4)--(0,4);     \foreach \y in {-4,-3,...,4} {         \draw (0 - 0.1,\y) -- (0+0.1,\y);         \draw (\y,0 - 0.1) -- (\y,0+0.1);     }      %Nodes:     \node (a0) at (-4,-4) {};     \draw[fill] (a0) circle [radius=1.5pt];     \node (a1) at (-2,4) {};     \draw[fill] (a1) circle [radius=1.5pt];     \node (a2) at (2,-2) {};     \draw[fill] (a2) circle [radius=1.5pt];     \node (a3) at (4,2) {};     \draw[fill] (a3) circle [radius=1.5pt];               \draw (-4,-4) to (-2,4) to (2,-2) to (4,2); % to (a2) to (a3);  \end{tikzpicture}   I'm trying to to get a line between them (the dots) that will be like a function (not a straight line - a curve like a polynomial).  Is this possible?  Thank you!

It's not really a typical math question. Today, while studying graphs, I suddenly got inquisitive about whether there exists a function that could possibly draw a heart-shaped graph. Out of sheer curiosity, I clicked on Google, which took me to .  The page seems informative, and I am glad to learn certain new things! Now I am interested in drawing them by my own using Mathematica. So my question is: is it possible to draw them in Mathematica? If yes, please show me how.

i think if the graph G has an odd cycle, it's not two-colorable, otherwise it can be two colorable.   i read in one notes that the following is True: we couldent two-colorable any graph G that has cycle.    anyone could clarify me ?

Suppose that we are given two graphs on a relatively small number of vertices. Here's an example:    Are these two graphs isomorphic? (That is: is there a bijection $f$ from $\{A,B,\dots,I\}$, the vertex set of the first graph, to $\{1,2,\dots,9\}$, the vertex set of the second graph, such that $vw$ is an edge of the first graph if and only if $f(v)f(w)$ is an edge of the second graph?)   If not, how can we tell? If so, how can we tell—and how can we find an isomorphism?     This question comes up a lot, usually asking about specific examples of two graphs which may or may not be isomorphic. Sometimes, the fiendish teacher of graph theory will even give three or more graphs and ask "Which of these are isomorphic?"  I'm asking this question so that we can provide  to questions of this type which would be worth linking to when specific instances of this question come up. So all improvements and/or suggestions are welcome!

I want to make various copies of a graph in tikz. The graph I want has 10 vertices. But only has the edges between the vertices a_i,a_(i+1),t,b.  I would like to automatically create 8 copies of this graph. and draw them. I just don't know how to code it. Here is my current code, but it adds all of the edges to the same copy of the graph:  \begin{tikzpicture} [main_node/.style={circle,fill=blue!20,draw,minimum size=2em,inner sep=3pt]}] \node[main_node] (8) at (0:0.5) {b}; \node[main_node] (9) at (180:0.5) {t}; \foreach \x in {0,1,...,7}     \node[main_node] (\x) at (360/8*\x:2) {$a_{\x}$}; \foreach \x in {0,1,...,7}{     \pgfmathsetmacro{\y}{int(mod(\x+1,8))}     \path[draw,thick] (\x) edge node {} (8);     \path[draw,thick] (\x) edge node {} (9);     \path[draw,thick] (\x) edge node {} (\y);     \path[draw,thick] (8) edge node {} (9);     \path[draw,thick] (8) edge node {} (\y);     \path[draw,thick] (9) edge node {} (\y);    }   I want each of the edge sets to be drawn seperately.

Hello i have the following graph:    I'm trying to figure out if it's planar or not. I think it is not planar but i can't find a subgraph that is a subdivision of K3,3 or K5 , to use the kuratowski theorem.  p.s. i can only redraw the graph to show that it is planar or prove that       its not planar with kuratowski theorem. NO other methods allowed.

Can anybody explain as how to plot a graph of $|x| + |y| = 1$. Here $|x|$ and $|y|$ are absolute values.

How to draw nearly-arbitrary curved lines simply? For example, how to draw this graph:    Source Introduction to Algorithms (3rd edition) by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, Clifford Stein | Page 45 | Figure 3.1  Now I have two ideas of how to draw such figures:   Divide each curved line to many smaller curved lines which can be drawn by a TikZ command, for example  \draw (0,0) to [in=80, out=-30] (3,2);   This way is quite natural. However, it is difficult to divide, for instance, the lines in the above figure, in this way. Also, when I have already divided, it is very possible that I will get confused with the coordinates. Find a formula for each of the curved line, and then draw the graph of the curved line.  This way is good for normal graphs, but for the complicated curved lines as in the above figure, it seems to be impossible.   So none of the ways stated is good enough. Do you have any idea to draw such figures? Your help is much appreciated!     Notes   I'm sorry if the question is a duplicate. I have searched for a while without success. Your help will be great if you can help me draw the above figure. However, I strongly prefer a general solution for this, because the aim of the question is not just to ask how to draw the figure only. You can see that there is no MWE in my question. As I explained above, all of my idea so far are just bad, so I haven't applied any of them. I strongly prefer using TikZ. However, answers using PGF, PStricks, etc. are all very useful to me.
