我一直在尝试在 latex 中创建此图表，使用 tikz 绘制此图表的最简单、最灵活的方法是什么？谢谢！
答案1
这是又一次尝试。
代码
\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart,arrows, fit,positioning}
\tikzset{block/.style = {rectangle, draw, text width=4cm, text centered, rounded corners, minimum height=2.5cm},
block2/.style = {rectangle, draw, text width=4cm, text centered, minimum height=2.5cm},
arrow/.style={draw, -latex'}}

答案2
也许这会对你有所帮助。这是最灵活的方法。可能有很多 TikZ 包可以绘制这样的图表，需要的代码更少，但你不会有这种灵活性。在这里你可以改变一切（坐标、形状、箭头类型、颜色、位置……）。大多数代码只是复制/粘贴/更改属性。
