[Tex/LaTex] How to make nodes to simple dots instead of being named

nodestikz-pgf

I currently have the following code:

\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[scale=1]
\tikzstyle{every node}=[draw,shape=circle]
\path (0,0) node (p0) {$p_0$}
(-1.5,-1) node (p1) {$p_1$}
(-1.5,-2.5) node (p2) {$p_2$}
(1.5,-2.5) node (p3) {$p_3$}
(1.5,-1) node (p4) {$p_4$}
(0,-3.5) node (p5) { $p_5$};
\draw (p0) -- (p1)
(p0) -- (p1)
(p0) -- (p2)
(p0) -- (p3)
(p0) -- (p4)
(p0) -- (p5)
(p1) -- (p2)
(p1) -- (p3)
(p1) -- (p4)
(p1) -- (p5)
(p2) -- (p3)
(p2) -- (p4)
(p2) -- (p5)
(p3) -- (p4)
(p3) -- (p5)
(p4) -- (p5);
\end{tikzpicture}

\end{document}

but my problem is that this name each node. And i just want a simple dot.
How do I do that?

Best Answer

If you remove the $p_1$,...,$p_6$ from your code then you obtain

On another note, have a look at

Is there something like \providetikzstyle similar to \providecommand?

which details that \tikzstyle isn't an ideal command to use. I've used an alternative in my code below.

\documentclass{article}

\usepackage{tikz}


\begin{document}
\begin{tikzpicture}[every node/.style={draw,shape=circle,fill=blue}]
\path (0,0) node (p0) {}
(-1.5,-1) node (p1) {}
(-1.5,-2.5) node (p2) {}
(1.5,-2.5) node (p3) {}
(1.5,-1) node (p4) {}
(0,-3.5) node (p5) { };
\draw (p0) -- (p1)
(p0) -- (p1)
(p0) -- (p2)
(p0) -- (p3)
(p0) -- (p4)
(p0) -- (p5)
(p1) -- (p2)
(p1) -- (p3)
(p1) -- (p4)
(p1) -- (p5)
(p2) -- (p3)
(p2) -- (p4)
(p2) -- (p5)
(p3) -- (p4)
(p3) -- (p5)
(p4) -- (p5);
\end{tikzpicture}


\end{document}
