使用森林包制作树的遍历动画

Question

我正在尝试制作树遍历的动画。我希望在不同的页面上用圆圈标记树的不同节点，例如最顶层的第一个节点，在下一张幻灯片上标记下一层级的第二个节点。

我的最小工作示例：

\documentclass[18pt,xcolor=table]{beamer}

\usepackage[linguistics]{forest}
\begin{document}
\begin{frame}{Access Operations - Basic Procedure}
\begin{figure}
\centering
\scalebox{0.8}{
\begin{forest}for tree={inner sep=0pt,outer sep=0pt, s sep=(3-level)*2mm, l=(125-level*level*level)*0.1mm}
  [,s sep=30
    [1, circle, draw
      [1, circle, draw
        [1]
        [1]
        [0]
        [0]
      ]
      [1
        [1]
        [0]
        [0]
        [0]
      ]
      [0]
      [1
        [0]
        [0]
        [0]  
        [1]
      ]
    ]
    [0]
    [1
      [0]
      [1
        [0]
        [1]
        [0]
        [1]
      ]
      [0]  
      [0]    
    ]
    [1
      [1
        [1]
        [1]
        [1]
        [0]
      ]
      [0]
      [0]
      [0]    
    ]
  ]
\end{forest}}
\end{figure}

\end{frame}
\end{document}

生成的树的两个节点均已标记： 我想在第一张幻灯片上标记一个，在下一张幻灯片上标记另​​一个。（我尝试过，仅可见）

Answer 1

这是我用来创建样式的代码的一部分的修改draw on。我使用的代码是从其他答案中继承而来的，如下面的评论中所述。我更改了节点是否被绘制，但没有更改它是否是圆形，以避免尺寸不一致。
