Tikz - Draw path of arrow [Updated]

Question

I need to draw a path of arrow like this :

I have try this code :

\documentclass[tikz, border=2mm]{standalone}
\begin{document}
    \begin{tikzpicture}[scale=2]
        \node[circle, draw=black] (A) at (0,0){A};
        \node[circle, draw=black] (B) at (1,0){B};
        \node[circle, draw=black] (C) at (2,0){C};
        \node[circle, draw=black] (D) at (3,0){D};
        \draw[->] (A) -- (B) -- (C) -- (D);
    \end{tikzpicture}
\end{document}

But i have something like that :

How to do that ?

EDIT : I change the post

You need to provide us a small compiling example that shows what you tried. Please edit your question — Steven B. Segletes, Apr 18 '21 at 00:27

Or: \draw (A) edge[->] (B) (B) edge[->] (C) (C) edge[->] (D); — hpekristiansen, Apr 19 '21 at 09:32

Update : with the graphs library

The graphs library allows you to do this in a simple and concise way. See the section 19.2.2 Concept: Chain Groups in the pgfmanual

\documentclass[tikz, border=5mm]{standalone}
\usetikzlibrary {graphs}
\begin{document}
\tikz\graph[grow right=20mm,nodes={draw, circle,fill=cyan!30}] {A -> B -> C -> D};
\end{document}

First answer: with the chains library

The chains library allows you to do this. See section 48 Chains of the pgfmanual.

\documentclass[tikz, border=2mm]{standalone}
 \usetikzlibrary {chains}
\begin{document}
\begin{tikzpicture}[node distance=20mm, on grid,
every node/.style=draw,circle,every join/.style=->]
\begin{scope}[start chain]
\node [draw,on chain,join] {A};
\node [draw,on chain,join] {B};
\node [draw,on chain,join] {C};
\node [draw,on chain,join] {D};
\end{scope}
\end{tikzpicture}
\end{document}

Similar to that in @AndréC's answer (+1), but with a bit shorter code:

\documentclass[tikz, border=2mm]{standalone}
\usetikzlibrary{arrows.meta,
                chains}
\begin{document}
\begin{tikzpicture}[
node distance = 20mm, on grid,
  start chain = going right,
every node/.style = {circle, draw, on chain, join=by -{Straight Barb[scale=0.8]}}
                    ]
\node {A};
\node {B};
\node {C};
\node {D};
\end{tikzpicture}
\end{document}
