我是 tikz 绘图的新手，现在我遇到的问题是我不知道如何绘制源自 tikz 节点的弯曲箭头，以及如何更改节点的 tex 大小。以下是我的代码。非常感谢您的帮助。

我喜欢使用矩阵来放置节点，如下所示：
\documentclass[tikz]{standalone}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}[font=\tiny,>=latex,]
\tikzset{
state/.style={circle,draw=black,minimum size=1em,inner sep=0pt},
% mypic
pics/mypic/.style={code={
\tikzset{mypic/.cd,#1}
\def\pv##1{\pgfkeysvalueof{/tikz/mypic/##1}}%
\edef\m{\pv{m}}%
\edef\w{\pv{size}}%
\foreach \row [count=\j] in \m {
\foreach \x [count=\i] in \row {
\node[state] (N-\j-\i)at
(\i*\w-\w,-\j*\w+\w) {\x};
}%foreach
}%foreach
}},mypic/.cd,m/.initial={{0}},size/.initial=1,/tikz/.cd,
%
% mypic
pics/myann/.style={code={
\draw [->,green!30!black, dotted,scale=0.6] (0,0) --++(1,0) node [right,text=black] {A};
\draw [->,blue, dashed,scale=0.6] (0,-0.5) --++(1,0) node [right,text=black] {B};
\draw [->,violet,scale=0.6] (0,-1) --++(1,0) node [right,text=black] {C};
\draw [->,red, dash dot,scale=0.6] (0,-1.5) --++(1,0) node [right,text=black] {D};
}},myann/.cd,/tikz/.cd,
%
}
\def\clst{
{w},
{18,w,w,w},
{17,10,7,6},
{10, 9, 6, 5},
{8, 8, 5, 4, w/2},
{4, 4, 4, 3, 3},
{2, 2, 2, 2, 2},
{1, 1, 1, 1, 1}%
}
\matrix (M) {
\pic{mypic={m=\clst,size=1cm}};\\
};
\foreach \j in {1,...,4} {
\foreach \i [evaluate=\i as \k using int(\i-1)] in {8,7,...,3} {
\ifnum\i<5
\tikzset{linestyle/.style={violet,dotted}}
\else
\ifnum\i=5
\tikzset{linestyle/.style={violet}}
\else
\tikzset{linestyle/.style={blue,dashed}}
\fi
\fi
\draw[every loop, line width = 0.12mm]
(N-\i-\j) edge[linestyle] node {} (N-\k-\j);
}
}
\draw[every loop, line width = 0.12mm]
(N-2-1) edge[violet, dashed] node {} (N-1-1);
\foreach \i in {1,2,...,8} {
\draw[->] (N-\i-1.east) to[bend left] ++ (-45:0.5);
}
\matrix[right=0 of N-2-4.north east,anchor=south west] (N) {
\pic{myann};\\
};
\end{tikzpicture}
\end{document}
