How To Display Images in a Diagram Frame by Frame in Beamer

Question

I wrote the following tikz code

\documentclass[10pt]{beamer}
\usetheme{Warsaw}
\usetikzlibrary{calc, shapes, snakes, decorations.markings, patterns, , arrows.meta}
\usetikzlibrary{backgrounds} % For testing with "framed" option to look at the bounding box
\newcommand{\smallbead}[1]{\draw[fill] #1 circle [radius=0.1em]}

\begin{document}
\begin{frame}
\begin{figure}[H]
    %\label{}
    \centering
    \begin{tikzpicture}[
    single arrow/.style = {decoration={markings, mark=at position 0.5 with {\arrow{>}}}, postaction={decorate}},
    double arrow/.style = {decoration={markings, mark=at position 0.5 with {\arrow{>>}}}, postaction={decorate}},
    hatched/.style = {pattern=north west lines, opacity=0.3},
    ]
\begin{scope}[xshift=2cm]
        \coordinate (F1) at (-1, 2);
        \coordinate (F2) at (1, 2);
        \coordinate (E1) at (-2, 1);
        \coordinate (E3) at (0, 1);
        \coordinate (E2) at (2, 1);
        \coordinate (V) at (0, 0);

        \node [circle, above left] at (F1) {$f_1$};
        \node [above right] at (F2) {$f_2$};
        \node [left] at (E1) {$e_1$};
        \node [right] at (E2) {$e_2$};
        \node [above] at (E3) {$e_3$};
        \node [below] at (V) {$v$};

        \smallbead{(F1)};
        \smallbead{(F2)};
        \smallbead{(E1)};
        \smallbead{(E2)};
        \smallbead{(E3)};
        \smallbead{(V)};
        \draw [single arrow] (V) [bend left] to (E1);
        \draw [single arrow] (V) [bend right] to (E1);
        \draw [single arrow] (V) [bend left] to (E3);
        \draw [single arrow] (V) [bend right] to (E3);
        \draw [single arrow] (V) [bend left] to (E2);
        \draw [single arrow] (V) [bend right] to (E2);
        \draw [single arrow] (E1) to (F1);
        \draw [single arrow] (E1) to (F2);
        \draw [single arrow] (E2) to (F1);
        \draw [single arrow] (E2) to (F2);
\end{scope}
\end{tikzpicture}
\end{frame}
\end{document}

to generate the following diagram

I want to use this diagram while giving a presentation.

For better exposition, I want to display diagram not in one single frame but in 3 different frames.

The first frame is supposed to display only the dots and their labels.

The second frame is supposed to display the contents of the first frame along with the arrows from the lowest level to the intermediate level.

The third frame is supposed to display the whole of the diagram.

Of course, I can achieve this my writing 3 different codes, one for each frame. But is there a smarter way?

EDIT: I have used a user-defined command \smallbead to but dots at the places I want.

@Faekynn solution to suit your example

\documentclass{beamer}

\usepackage{tikz}

\begin{document}

\frame{\frametitle{unnumbered lists}
\begin{tikzpicture}[xshift=2cm]
\only<1-3>{
        \coordinate (F1) at (-1, 2);
        \coordinate (F2) at (1, 2);
        \coordinate (E1) at (-2, 1);
        \coordinate (E3) at (0, 1);
        \coordinate (E2) at (2, 1);
        \coordinate (V) at (0, 0);
        }
\only<2-3>{
        \node [circle, above left] at (F1) {$f_1$};
        \node [above right] at (F2) {$f_2$};
        \node [left] at (E1) {$e_1$};
        \node [right] at (E2) {$e_2$};
        \node [above] at (E3) {$e_3$};
        \node [below] at (V) {$v$};
} 
\only<3>{
        \draw [->] (V) [bend left] to (E1);
        \draw [->] (V) [bend right] to (E1);
        \draw [->] (V) [bend left] to (E3);
        \draw [->] (V) [bend right] to (E3);
        \draw [->] (V) [bend left] to (E2);
        \draw [->] (V) [bend right] to (E2);
        \draw [->] (E1) to (F1);
        \draw [->] (E1) to (F2);
        \draw [->] (E2) to (F1);
        \draw [->] (E2) to (F2);
        }

\end{tikzpicture}

}

\end{document}

Answer 2

You can use the \only command to show some content only a some slides of a frame. This works for everything, not only for tikz-pictures.

I also cleand up the code a little bit to contain only relevant things for the picture....

\documentclass[]{beamer}
\usepackage{tikz}
\usetikzlibrary{decorations.markings, arrows.meta}
\newcommand{\smallbead}[1]{\draw[fill] #1 circle [radius=0.1em]}

\begin{document}
\begin{frame}
    \begin{tikzpicture}[ single arrow/.style = {decoration={markings, mark=at position 0.5 with {\arrow{>}}}, postaction={decorate}},  ]
        \coordinate (F1) at (-1, 2);
        \coordinate (F2) at (1, 2);
        \coordinate (E1) at (-2, 1);
        \coordinate (E3) at (0, 1);
        \coordinate (E2) at (2, 1);
        \coordinate (V) at (0, 0);

        \node [circle, above left] at (F1) {$f_1$};
        \node [above right] at (F2) {$f_2$};
        \node [left] at (E1) {$e_1$};
        \node [right] at (E2) {$e_2$};
        \node [above] at (E3) {$e_3$};
        \node [below] at (V) {$v$};

        \smallbead{(F1)};
        \smallbead{(F2)};
        \smallbead{(E1)};
        \smallbead{(E2)};
        \smallbead{(E3)};
        \smallbead{(V)};

        \only<2->{  % show this content only from the second slide onwards
        \draw [single arrow] (V) [bend left] to (E1);
        \draw [single arrow] (V) [bend right] to (E1);
        \draw [single arrow] (V) [bend left] to (E3);
        \draw [single arrow] (V) [bend right] to (E3);
        \draw [single arrow] (V) [bend left] to (E2);
        \draw [single arrow] (V) [bend right] to (E2);
        }
        \only<3>{ % only on third slide
        \draw [single arrow] (E1) to (F1);
        \draw [single arrow] (E1) to (F2);
        \draw [single arrow] (E2) to (F1);
        \draw [single arrow] (E2) to (F2);
       }
\end{tikzpicture}
\end{frame}
\end{document}
