帮助在乳胶中绘制一个图：一个带有 8 个箭头的圆形节点

在此处输入图片描述 你好，我想画下图。有人能帮我吗？

太感谢了。

这里还有另一个示例供您入门。它用于\foreach使事情变得紧凑。

\documentclass[tikz]{standalone}
\begin{document}
\begin{tikzpicture}[
mycirclestyle/.style={draw,fill=blue!50,circle, minimum size=1cm,inner sep=2pt},
myarrowstyle/.style={stealth-,
    line width=1.5mm,
    draw=green!50,}
]
\node[mycirclestyle,name=circle] at (0,0) {A};
\foreach \direction/\angle/\anchordir/\ttext in {north/90/south/2, north east/45/south west/1, east/0/west/2, south east/-45/north west/4, south/-90/north/8, south west/-135/north east/5, west/-180/east/4, north west/135/south east/3}
{\draw[myarrowstyle](circle.\direction)--++(\angle:1cm)node[anchor=\anchordir]{\ttext};}
\end{tikzpicture}
\end{document}

中心为圆形节点的图片，带有径向箭头

根据评论的要求进行一些修改：

\documentclass[tikz]{standalone}
\begin{document}
\begin{tikzpicture}[
mycirclestyle/.style={draw,fill=blue!50,circle, minimum size=1cm,inner sep=2pt},
myarrowstyle/.style={stealth-,
    line width=1.5mm,
    draw=green!50,}
]
\node[mycirclestyle,name=circle] at (0,0) {A};
\foreach \direction/\angle/\anchordir/\ttext in {
north/90/south/Very very smart\\ \& efficient, 
north east/45/south west/dumb and\\ \& boring, 
east/0/west/2, 
south east/-45/north west/4, 
south/-90/north/8, 
south west/-135/north east/5, 
west/-180/east/4, 
north west/135/south east/3
}
{\draw[myarrowstyle](circle.\direction)--++(\angle:1cm)node[anchor=\anchordir,align=center,font=\tiny]{\ttext};}
\end{tikzpicture}
\end{document}

中心为圆形节点的图片，带有径向箭头

对于练习...作为起点使用@Matthias Arras 回答：

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows.meta}

\begin{document}
\begin{tikzpicture}[
A/.style = {{Triangle[angle=90:1pt 1.5]}-, line width=2mm, 
            draw=green!50, shorten <=1pt},
C/.style = {draw,fill=blue!50,circle, minimum size=1cm,inner sep=2pt},
every label/.append style = {label distance=0pt, inner sep=0pt, align=center,
                             font=\small\linespread{0.84}\selectfont}
]
\node (c) [C] {A};
\foreach \angle/\j in {45/{some\\ text},
                        90/{very smart\\\& efficient},
                        135/{dump and\\boring},
                        180/4, 225/5, 270/6,315/7,360/8}
{
\draw[A](c.\angle) --++ (\angle:1) node[coordinate,label=\angle:\j] {};
}
    \end{tikzpicture}
\end{document}

我已经使用了通常的工具（Mathcha）在线更快地创建使用的 MWE 代码TikZ，因为 OP 没有 MWE 而只有一张图片。
