How to draw complicated flow chart in latex?

Question

Welcome to TeX.SX. Questions about how to draw specific graphics that just post an image of the desired result are really not reasonable questions to ask on the site. Please post a minimal compilable document showing that you've tried to produce the image and then people will be happy to help you with any specific problems you may have. See minimal working example (MWE) for what needs to go into such a document. — Stefan Pinnow, Apr 13 '18 at 10:00

With basic tools (mathtools, \raisebox) and some trial and error (not sure of the final circle arrow):

\documentclass{article}

\usepackage{mathtools, amssymb}

\begin{document}

\[ \begin{rcases}
  \mathrm{A}\\[1ex]\mathrm{B}
\end{rcases}\implies \raisebox{-0.34\height}{$\begin{rcases}\mathrm{C}\\[1ex]\mathrm{D} \end{rcases}\implies \raisebox{0.53\height}{$\begin{rcases}\mathrm{F}\\[1ex]\mathrm{E} \end{rcases}\circlearrowleft$}$}\]%

\end{document}

I upvote your answer. Very nice. Why you have added \circlearrowleft? – Sebastiano Apr 13 '18 at 10:17

That's because I thought it wasn't a G but a circled arrow. Not too sure, though, as it's hand written… – Bernard Apr 13 '18 at 10:20

\documentclass[border = 5pt]{standalone}

\usepackage{relsize}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing}
\usetikzlibrary{decorations.markings}
\usetikzlibrary{positioning}
\usetikzlibrary{arrows}


\begin{document}

\begin{tikzpicture}[
  my node/.style={font = \relsize{30}},
  brace/.style={decoration = {brace, raise = 5pt}, decorate},
  dblarrow/.style={thick, decoration={markings, mark = at position
      1 with {\arrow[semithick]{open triangle 60}}},
    double distance=1.4pt, shorten >= 5.5pt,
    preaction = {decorate},
    postaction = {draw,line width=1.4pt, white,shorten >= 4.5pt}}
  ]

  \node[my node] (A) {A};
  \node[my node, below = of A] (B) {B};
  \draw[brace] (A.north east) -- node[midway, outer sep = 10pt] (AB) {} (B.south east);

  \node[my node, right = of AB] (C) {C};
  \node[my node, below = of C] (D) {D};
  \draw[dblarrow] (AB.east) -- (C.west); 
  \draw[brace] (C.north east) -- node[midway, outer sep = 10pt] (CD) {} (D.south east);

  \node[my node, right = of CD] (E) {E};
  \node[my node, above = of E] (F) {F};
  \draw[dblarrow] (CD.east) -- (E.west); 
  \draw[brace] (F.north east) -- node[midway] (FE) {} (E.south east);

  \node[my node, right = of FE] (G) {G};
\end{tikzpicture}

\end{document}

+1 very nice code. I don't like the arrows. :( – Sebastiano Apr 13 '18 at 10:15 — Sebastiano, Apr 13 '18 at 10:15
@Sebastiano My apologies for that – caverac Apr 13 '18 at 12:06 — caverac, Apr 13 '18 at 12:06

While it's certainly feasible to use a matrix/table to accomplish what you are trying to do, I'd suggest to have a look at Graphviz.

It uses a textual representation of the relationship of your items and produces a nice looking graph that you can export to PDF (and include as image).
