如何绘制这样的树形图？

```c
\documentclass[tikz]{standalone}
\usepackage{tikz}
\usetikzlibrary{graphs,graphdrawing,}
\usegdlibrary{layered}
\begin{document}
\begin{tikzpicture}
\graph [
layered layout,
nodes={draw,minimum height=3em,text width=5em,align=center,rounded corners},
level distance=2cm,
sibling distance=5mm,
]
{
Adversarial example ->
{
Attack ->
{
Knowledge based ->
{
/"White-box",
/"Black-box"
},
Target based ->
{
Targeted,
/"Non-targeted"
}
},
Defense ->
{
Detection,
Model Enhancement ->
{
Adversarial training,
Network construction,
Testing,
Verification
}
}
}
};
\end{tikzpicture}
\end{document}
```
这个例子需要 LuaLaTeX 编译，图的细节方面可能不太容易调整，还是等待其他更好的回答吧

这个图，可能要用 `tikz` 的 `\usetikzlibrary{trees}` 吧。早年画过一个，后来就不想再用它画图了。
```
\documentclass{ctexart}
\usepackage{tikz}
\usetikzlibrary{trees}
\begin{document}
\begin{tikzpicture}
\node{$ A $对称}[
font=\small,
edge from parent fork right,
grow=right,
edge from parent/.append style = {-latex},
level 1/.style = {level distance = 14ex, sibling distance=10em},
level 2/.style = {level distance = 19ex, sibling distance=5em},
level 3/.style = {level distance = 19ex, sibling distance=3em},
level 4/.style = {level distance = 26ex, sibling distance=6em}
]
child{node{$ A^T $可用}
child{node{存储花费大}
child{
node{
\fbox{
\begin{minipage}{11ex}
\textbf{GMRES},\\
FOM, GCR
\end{minipage}
}
}
edge from parent node[near end,above] {N}
}
child{node[text width = 12ex]{$ A $有复特征值}
child{
node{
\fbox{
\begin{minipage}{13ex}
\textbf{BiCGSTAB}\\
BiCRSTAB\\
CGS\\
GPBiCG\\
QMRCGSTAB\\
TFQMR
\end{minipage}
}
}
edge from parent node[near end,above] {N}
}
child{
node{
\fbox{
\begin{minipage}{13ex}
BiCGSTAB($ l $)\\
IDR($ s $)
\end{minipage}
}
}
edge from parent node[near end,above] {Y}
}
edge from parent node[near end,above] {Y}
}
edge from parent node[near end,above] {N}
}
child{node{$ A $条件数好}
child{node{BiCG, QMR} edge from parent node[near end,above] {N}}
child{node{CGNR, CGNE} edge from parent node[near end,above] {Y}
}
edge from parent node[near end,above] {Y}
}
edge from parent node[near end,above] {N}
}
child{node{$ A $正定}
child{node{$ A $条件数好}
child{node{MINRES, MR} edge from parent node[near end,above] {N}}
child{node{CGNR, CGNE}
edge from parent node[near end,above] {Y}}
edge from parent node[near end,above] {N}
}
child{node[text width=4\ccwd]{\textbf{CG}} edge from parent node[near end,above] {Y}}
edge from parent node[near end,above] {Y}
};
\end{tikzpicture}
\end{document}
```
