如何通过以下方式为 Tikz 制作动画

Question

我希望这个 tikz 图片能够按如下方式进行动画处理：

\documentclass[border=2mm,tikz]{standalone}
\usepackage{tikz}
\usetikzlibrary{decorations.text, fit}
\usetikzlibrary{positioning,fit,backgrounds,arrows.meta}
\begin{document}
    \begin{tikzpicture}[scale=2,
        fatnode1/.style={rectangle, draw=blue, rounded corners, fill=blue!20, minimum size=0.0mm},
        fatnode2/.style={rectangle, draw=red, rounded corners, fill=red!20, minimum size=0.0mm},
        font=\sf,
        >=Latex,
        thick,
        node distance=1.2]
        \node[fatnode1] (A) at (0, 0) {Data Importation};
        \node[fatnode1, right=of A] (B) {Data Cleaning};
        \node[fatnode2, right=of B] (C) {Data Wrangling};
        \node[fatnode2, above right=of C] (D) {Data Visualization};
        \node[fatnode1, below right=of C] (E) {Data Modeling};
        \node [xshift=1.2cm, right=of C] (F) {};
        \begin{pgfonlayer}{background}
        \node [fill=blue!10, rounded corners, fit= (C) (D) (E) (F)] (H) {}; % enough to add two diagonal nodes
        \end{pgfonlayer}
        \node[fatnode2, fill=white] (I) at (H.220) {\footnotesize Data Exploration};
        \node[fatnode1, right=of H] (G) {Communicate Resuls};
        \draw [thick, ->] (A) -- (B);
        \draw [thick, ->] (B) -- (C);
        \draw [thick, ->] (H) -- (G);
        \draw [->,thick] (C) to [bend left=40]  (D);
        \draw [->,thick] (D) to [bend left=45]  (E);
        \draw [->,thick] (E) to [bend left=45]  (C);
        \node[draw, rounded corners, fit=(A) (B) (C) (D) (E) (G) (H) (I)] {};
    \end{tikzpicture}

\end{document}

• 我想Data Importation出现，然后Data Cleaning出现。

• 我想要Circle随之旋转Data Wrangling，Data Visualization，Data Modeling。

• 我希望Communicate Result然后出现。

这个答案我对此很感兴趣，但我无法就我自己的情况弄清楚。

beamer这是叠加层和包的组合animate，用于显示图示所需的步骤并使箭头动起来。动画箭头是借助decorations.markings库放置的。

被tikzpicture包裹在一个命令中以接受参数（步骤 ID、箭头位置）。此外，还需要调整其大小以使其适合幻灯片beamer。

\documentclass{beamer}

\usepackage{tikz}
\usetikzlibrary{decorations.text, decorations.markings}
\usetikzlibrary{positioning,fit,backgrounds,arrows.meta}
\usepackage{animate}

\newcommand\steppedChart[2]{%
