Modifying a circular chart diagram code

Question

I would like to make some modifications for this code from the answer to this question by Claudio Fiandrino

\usetikzlibrary{arrows,automata,positioning}
\usepackage{verbatim}
\usetikzlibrary{calc,shadows}

\pgfmathtruncatemacro{\adv}{\xi + 1)}
\edef\col{\@nameuse{color@\xi}}

\makeatother
%end for smartart
\begin{document}
\begin{frame}{Smart art}
\begin{center}
\smartartov{Low economic growth,Low income,Low saving,Low investment}
\end{center}
\end{frame}
\end{document}

which produces the following animated figure

1. The cycle to be clockwise not anticlockwise

2. Double circles as in the lower figure

3. no animation

to look like

Unfortunately, I can not use smartdiagram. I can not install packages on my workplace computer for security reasons.

Answer 1

This is what you could do with plain TikZ.

\documentclass{beamer} 
\usepackage{tikz}
\usetikzlibrary{calc,shadows.blur,positioning,arrows.meta,bending} 
\begin{document}
\begin{frame}[fragile,t]
\frametitle{Smart art}
\begin{center}
 \begin{tikzpicture}[box/.style={rounded corners,blur shadow,text=white,align=center,
      minimum width=2.2cm, minimum height=1.9cm,fill=#1},
      node distance=5mm and 0mm,
      arr/.style={line width=1mm,-{Stealth[bend]},shorten >=7pt,shorten <=7pt}]
  \node[box=cyan] (TL) {Low\\ economic\\ growth};
  \node[box=purple!50!red,below right=of TL,font=\Large] (M) {Low\\ income};
  \node[box=purple!50!red,below left=of TL] (L) {Low\\ investment};
  \node[box=purple,below right=of L,font=\Large] (BL) {Low\\ saving};
  \node[box=cyan,above right=of M] (TR) {Low level of\\ education\\ and  health\\ care};
  \node[box=purple,below right=of M] (BR) {Low\\ productivity};
  \node[box=blue!80,below right=of TR] (R) {Low levels\\ of human\\ capital};
  %
  \draw[arr] (L.80)  to[bend left=45] (TL.190);
  \draw[arr] (TL.-10)  to[bend left=45] (M.100);
  \draw[arr] (M.80)  to[bend left=45] (TR.190);
  \draw[arr] (TR.-10)  to[bend left=45] (R.100);
  \draw[arr] (R.-100)  to[bend left=45] (BR.10);
  \draw[arr] (BR.170)  to[bend left=45] (M.-80);
  \draw[arr] (M.-100)  to[bend left=45] (BL.10);
  \draw[arr] (BL.170)  to[bend left=45] (L.-80);
  %
  \node[below=1mm of TL,font=\large,orange] {Growth};
  \node[below=1mm of TR,font=\large,orange] {Development};
 \end{tikzpicture}
\end{center} 
\end{frame}
\end{document}
