如何向思维导图添加信息

Question

我想在思维导图中添加一些信息。我正在尝试遵循一个示例这里但每当我尝试通过此命令添加时

(\node at (88.000:27em) [anchor = west] {next: this is next test};)

它以与其他节点相同的圆形节点的形式向我提供该信息。我想要做的是添加图例（不需要符号）类型的方块，我可以在其中添加有关一些缩写的信息（更可取）或仅注释节点。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{mindmap}
\begin{document}    
\begin{figure*}[!ht]
    \centering
    \begin{tikzpicture}[baseline, mindmap, grow cyclic, text width=2.5cm, minimum size=1cm, align=flush center, every node/.style=concept, concept color=violet=!30,
        level 1/.append style={level distance=3.5cm,sibling angle=135},
        level 2/.append style={level distance=3.0cm,sibling angle=60},
        level 3/.append style={level distance=2.5cm,sibling angle=50},
        level 4/.append style={level distance=2.0cm,sibling angle=60},
        ]
        \node  [left color=violet!40, middle color=red!10, right color=white!30]{\textbf{Checking}}

我没有关于您想要实现什么的详细信息，但这只是告诉您从“外部”标记节点很简单。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,mindmap,arrows.meta,bending}
\begin{document}
\begin{figure*}[!ht]
\centering
\begin{tikzpicture}
 \begin{scope}[baseline, mindmap, grow cyclic, minimum size=1cm, align=flush center, 
 every node/.style={concept,inner sep=0pt}, concept color=violet=!30,
    level 1/.append style={level distance=3.2cm,sibling angle=120},
    level 2/.append style={level distance=0.7*3.0cm,sibling angle=60},
    level 3/.append style={level distance=0.7*2.5cm,sibling angle=50},
    level 4/.append style={level distance=0.7*2.0cm,sibling angle=60},
    ]
    \node  [left color=violet!40, middle color=red!10, right
    color=white!30,font=\bfseries,inner sep=-5mm]{Checking}
        child [concept color=violet!50] { node [minimum size=0.5*2.0cm] {State}
    child [concept color=violet!30] { node [minimum size=0.5*1.5cm] {F}
        child [concept color=violet!30] {node [minimum size=0.5*1.5cm]  {T}}
        }
    child [concept color=violet!30] { node  {A123}
    child [concept color=violet!30] { node [minimum size=0.5*1.5cm] {12}}
    child [concept color=violet!30] { node [minimum size=0.5*1.5cm] {random}}

          }
          child [minimum size=0.5pt, concept color=violet!50] { node [minimum size=0.5*2.0cm] {Mix}
        child [concept color=violet!30] { node [minimum size=0.5*1.5cm]  {QR}}
        child [concept color=violet!30] { node [minimum size=0.5*1.5cm] {ST}}
        }

        }
