Graphics, Figures & Tables ⇒ Text and lines in a data-structure tree

[jhapk]

Hi,

I want to make a tree like this

However, my code gives me the following output

Here is my code

Code: Select all

\documentclass[12pt]{minimal}
\usepackage{tikz}
\begin{document}
\pagestyle{empty}

\begin{tikzpicture}
  [level distance=15mm,
  every node/.style={fill=black, rectangle, minimum size=2pt},
  level 1/.style={sibling distance=10mm},
  level 2/.style={sibling distance=0.5*10mm},
  level 3/.style={sibling distance=0.3*10mm}] 

  \node {}[grow=up]   
  child {node {}}
  child { node {}
    child {node {}}
    child { node {}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node [above] {D}}
      child {node {}}
      child {node {}}
    }
    child {node {}}
    child {node {}}
    child {node {}}
    child {node {}}
    child {node {}}
    child {node {}}
  }
  child {node {}}
  child {node {}}
  child {node {}}
  child { node {}
    child {node [above] {C}}
    child {node {}}
    child {node {}}
    child {node {}}
    child {node {}}
    child { node {}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
      child {node {}}
    }
    child {node {}}
    child {node {}}
  }
  child {node [above] {B}}
  child {node {}};
   
\end{tikzpicture}
\end{document}

Any ideas how do I place additional lines and text in the same scope and how do I place text on top of some desired node?

Thanks

Place appropriate nodes with the according text subsequently.

Hi,

Thanks localghost. That solved the problem. The present code gives me the desired tree structure.

Code: Select all

\documentclass{minimal}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
  [level distance=15mm,
  every node/.style={fill=black, rectangle, minimum size=2pt},
  level 1/.style={sibling distance=10mm},
  level 2/.style={sibling distance=0.5*10mm},
  level 3/.style={sibling distance=0.3*10mm}]  

  \node {}[grow=up]	
  child {node {}}
  child { node {}
    child {node {}}
    child { node {}
      child {node {}}
      child {node {}} 
      child {node {}}
      child {node {}}
      child {node {}}
