Я использую TikZ в первый раз, и я не знаю, как нарисовать эту таксономию.Tikz: рисунок диаграммы таксономии/классификации
мне удалось нарисовать 2 колонки, с помощью следующего кода:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes,snakes,positioning,shapes.misc}
\begin{document}
\begin{tikzpicture}
\node at (-3,1) [rectangle, aspect=0.5, draw=black!60,fill=black!20, inner sep=3pt, text width=2cm,,align=center](a){text text text};
\node at (-9,-1) [rectangle,draw](b1){text2};
\node at (-8.7,-2) [rectangle,draw](b2){text3};
\node at (-8.7,-3) [rectangle,draw](b3){text4};
\node at (-8.7,-4) [rectangle,draw](b4){text5};
\node at (-8.7,-5) [rectangle,draw](b5){text6};
\draw[->,thick] (a)--(0,0)--(-9,0);
\draw[->,thick] (-9,0)--(b1);
\draw[->,thick] ([xshift=0cm,yshift=0cm]b1.210)|-([]b2.west);
