Drawing sketches of Commutative Diagrams in LATEX:
\begin{tikzcd}[<options>]
<environment contents>
\end{tikzcd}
Inserting arrows:
Inside the {tikzcd} environment, the following synonymous commands are provided to produce arrows:
\arrow[<options>]
\ar[<options>]
If we want to draw a path with a middle arrow, just use:
\appendarrow{arrow size}{arrow color}{path}
For example,
\appendarrow{6pt}{black}{(-0.5, 0.125) to [out=60, in=120] (0.5, 0.125);}
A down arrow is created by the following command:
\Downarrow
Example 1:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node (x) at (0,0) {x};
\node (y) at (3,0) {y};
\draw[fill] (0.2,0) circle [radius=0.025];
\draw[fill] (2.8,0) circle [radius=0.025];
\draw [->] (x) -- (y)
\end{tikzpicture}
\end{document}
Example 2:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw[fill] (0,0) circle [radius=0.025];
\draw[fill] (3,0) circle [radius=0.025];
\draw [->] (0,0) -- (3,0);
\node [left] at (0,0) {x};
\node [right] at (3,0) {y};
\end{tikzpicture}
\end{document}
The requested picture:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw[fill] (0,0) circle [radius=0.025];
\draw[fill] (3,0) circle [radius=0.025];
\draw[fill] (6,0) circle [radius=0.025];
\draw (0,0) -- (6,0);
\node [above] at (0,0) {x};
\node [above] at (3,0) {y};
\node [above] at (6,0) {z};
\node (A) at (1.5,0) {$>$};
\node [above] at (A) {f};
\node (B) at (4.5,0) {$>$};
\node [above] at (B) {g};
