Newcomers wanting to use TikZ to create commutative diagrams face a varied (non-uniform) approach.
I found this simple method to create a commutative diagram:

documentclass{article}

usepackage[utf8]{inputenc}

usepackage{tikz}

begin{document}



$$begin{tikzpicture}[node distance=2cm, auto]

  node (C) {$C$};

  node (P) [below of=C] {$prod_{i in I} A_i$};

  node (Ai) [right of=P] {$A_i$};

  draw[->] (C) to node {$f_i$} (Ai);

  draw[->, dashed] (C) to node [swap] {$langle f_i rangle_{i in I}$} (P);

  draw[->] (P) to node [swap] {$pi_i$} (Ai);

end{tikzpicture}$$



end{document}

Which produces a neat commutative diagram:

I wished to adapt this for my own commutative diagram. The code is as below:

documentclass{article}

usepackage[utf8]{inputenc}

usepackage{tikz}

begin{document}



$$begin{tikzpicture}[node distance=2cm, auto]

  node (V) {$V$};

  node (FAI) [right of= V] {$FAI(V)$};

  node (CL) [below of= FAI] {$CL(V,q)$};

  draw[->] (V) to node (FAI);

  draw[->, dashed] (FAI) to node (CL);

  draw[->] (V) to node (CL);

end{tikzpicture}$$



end{document}

However, my diagram produces the compile error: "Package tikz Error: (, +, coordinate, pic, or node expected."

Reading on TeX, I have noticed users recommend alternative methods to draw commutative diagrams.

1. What are current best practices (best packages to use, etc.)


2. How do I use these best practise methods to accomplish my (simple) commutative diagram?

  Why don't use just use tikz-cd instead of doing it by hand? Regarding your code, I don't recall ever seeing to node (..) before. I'd probably just use -- instead. Also never use $$...$$, it is not LaTeX.

Here there is my version with tikz-cd. It is very easy to create simple and complex commutative diagrams.

Advice: do not worry about the background because It does not appear. Your initial code it is into this link.

documentclass{article}

usepackage[utf8]{inputenc}

usepackage{tikz-cd}

begin{document}



begin{tikzcd}

V arrow[r] arrow[rdd] & FAI(V) arrow[dd, dotted] \

 &  \

 & CL(V,q)

end{tikzcd}



end{document}

documentclass{article}

usepackage[utf8]{inputenc}

usepackage{tikz-cd}

begin{document}

begin{tikzcd}

C arrow[d, "langle f_i rangle_{i in I}"', dotted] arrow[rd, "f_i"] &  \

prod_{i in I} A_i arrow[r, "pi_i"'] & A_i

end{tikzcd}

Your code was almost correct, you just forgot the text label of the node.

Yours was like this:

draw[->] (V) to node (FAI);

but it must be like this:

draw[->] (V) to node {} (FAI);

or like this: (thanks @PaulGaborit)

draw[->] (V) to (FAI);

I made three of these corrections.

  node (V) {$V$};

  node (FAI) [right of= V] {$FAI(V)$};

  draw[->] (V) to node {} (FAI);% corrected here
