One possible approach is to (ab)use pgfmath:

```
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}

\def\mylist{{"foo","bar","baz"}}

\begin{document}

\begin{frame}
\frametitle{Demonstration}
\begin{tikzpicture}
\begin{scope}[every node/.style={fill=blue, circle,thick,draw, minimum size=1.3cm}]
    \node[label={[xshift=0em, yshift=-1em] \pgfmathparse{\mylist[  \insertslidenumber-1]}\pgfmathresult}]  (A) at (0,5) {A};
    \node[label={[xshift=0em, yshift=-1em] \pgfmathparse{\mylist[  \insertslidenumber-1]}\pgfmathresult}] (B) at (5,5) {B};
    \node[label={[xshift=0em, yshift=-1em] \pgfmathparse{\mylist[  \insertslidenumber-1]}\pgfmathresult}] (C) at (10,5) {C};
    \node[label={[xshift=-1em, yshift=-6em] \pgfmathparse{\mylist[  \insertslidenumber-1]}\pgfmathresult}] (D) at (0,0) {D};
    \node[label={[xshift=-1em, yshift=-6em] \pgfmathparse{\mylist[  \insertslidenumber-1]}\pgfmathresult}] (E) at (5,0) {E};
    \node[label={[xshift=-1em, yshift=-6em]  \pgfmathparse{\mylist[  \insertslidenumber-1]}\pgfmathresult}] (F) at (10,0) {F} ;
\end{scope}

\begin{scope}[>={Stealth[black]},
              every node/.style={fill=white,circle},
              every edge/.style={draw=red,very thick}]
    \path [-] (A) edge node {$1$} (B);
    \path [-] (D) edge node {$2$} (B);
    \path [-] (A) edge node {$3$} (D);
    \path [-] (D) edge node {$3$} (E);
    \path [-] (E) edge node {$2$} (F);
    \path [-] (E) edge node {$6$} (B);
    \path [-] (E) edge node {$4$} (C);
    \path [-] (B) edge node {$3$} (C);
    \path [-] (B) edge node {$5$} (F);
    \path [-] (F) edge node {$4$} (C);
\end{scope}
\end{tikzpicture}
\pause[3]
\end{frame}
\end{document}
```

It really depends on how you want to put in the lists. You can use arrays, too. ``` \documentclass{beamer} \usepackage{tikz} \usetikzlibrary{arrows.meta,overlay-beamer-styles} \makeatletter \tikzset{Alpha/.code 2 args={\edef#1{\@Alph{#2}}}} \makeatother \begin{document} \begin{frame} \frametitle{Demonstration} \begin{tikzpicture} \begin{scope}[every node/.style={fill=blue, circle,thick,draw, minimum size=1.3cm},scale=0.8] \node (A) at (0,5) {A}; \node (B) at (5,5) {B}; \node (C) at (10,5) {C}; \node (D) at (0,0) {D}; \node (E) at (5,0) {E}; \node (F) at (10,0) {F} ; \end{scope} \begin{scope}[>={Stealth[black]}, every node/.style={fill=white,circle}, every edge/.style={draw=red,very thick}] \path [-] (A) edge node {$1$} (B); \path [-] (D) edge node {$2$} (B); \path [-] (A) edge node {$3$} (D); \path [-] (D) edge node {$3$} (E); \path [-] (E) edge node {$2$} (F); \path [-] (E) edge node {$6$} (B); \path [-] (E) edge node {$4$} (C); \path [-] (B) edge node {$3$} (C); \path [-] (B) edge node {$5$} (F); \path [-] (F) edge node {$4$} (C); \end{scope} \edef\mylist{{2, 3, 5, 7, 11, 13}, {17, 19, 23, 29, 31, 37}, {41, 43, 47, 53, 59, 61}, {67, 71, 73, 79, 83, 89}, {97, 101, 103, 107, 109, 113}, {127, 131, 137, 139, 149, 151}} \foreach \X [count=\Step] in \mylist { \foreach \Y [count=\Z] in \X { \tikzset{Alpha={\my}{\Z}} \ifnum\Z<4 \path[visible on=<\Step>] (\my.north) node[above]{$\Y$}; \else \path[visible on=<\Step>] (\my.south) node[below]{$\Y$}; \fi }} \end{tikzpicture} \end{frame} \end{document} ``` ![ani.gif](/image?hash=cb9e21c0e9bebeb707cf651029488d79082a58b129796d57faf23eddac802be3)

Not sure if I understand the question, is this what you are looking for? ``` \documentclass{beamer} \usepackage{tikz} \usetikzlibrary{arrows.meta} \makeatletter \newcommand*{\slideinframe}{\number\beamer@slideinframe} \makeatother \def\mylist{{"foo","bar","baz"}} \begin{document} \begin{frame} \frametitle{Demonstration} \begin{tikzpicture} \begin{scope}[every node/.style={fill=blue, circle,thick,draw, minimum size=1.3cm}] \node[label={[xshift=0em, yshift=-1em] \pgfmathparse{\mylist[\slideinframe-1]}\pgfmathresult}] (A) at (0,5) {A}; \node[label={[xshift=0em, yshift=-1em] \pgfmathparse{\mylist[\slideinframe-1]}\pgfmathresult}] (B) at (5,5) {B}; \node[label={[xshift=0em, yshift=-1em] \pgfmathparse{\mylist[\slideinframe-1]}\pgfmathresult}] (C) at (10,5) {C}; \node[label={[xshift=-1em, yshift=-6em] \pgfmathparse{\mylist[\slideinframe-1]}\pgfmathresult}] (D) at (0,0) {D}; \node[label={[xshift=-1em, yshift=-6em] \pgfmathparse{\mylist[\slideinframe-1]}\pgfmathresult}] (E) at (5,0) {E}; \node[label={[xshift=-1em, yshift=-6em] \pgfmathparse{\mylist[\slideinframe-1]}\pgfmathresult}] (F) at (10,0) {F} ; \end{scope} \begin{scope}[>={Stealth[black]}, every node/.style={fill=white,circle}, every edge/.style={draw=red,very thick}] \path [-] (A) edge node {$1$} (B); \path [-] (D) edge node {$2$} (B); \path [-] (A) edge node {$3$} (D); \path [-] (D) edge node {$3$} (E); \path [-] (E) edge node {$2$} (F); \path [-] (E) edge node {$6$} (B); \path [-] (E) edge node {$4$} (C); \path [-] (B) edge node {$3$} (C); \path [-] (B) edge node {$5$} (F); \path [-] (F) edge node {$4$} (C); \end{scope} \end{tikzpicture} \pause[3] \end{frame} \end{document} ```
