如何在LaTeX中绘制复杂的流程图？
答案1
使用基本工具（mathtools，\raisebox）并进行一些反复试验（不确定最终的圆形箭头）：
\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}

\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}

虽然使用矩阵/表来完成您要做的事情确实是可行的，但我建议您看一下 Graphviz。
它使用文本表示您的项目关系并生成一个漂亮的图形，您可以将其导出为 PDF（并包含为图像）。
