Easy ball mindmaps

Since TikZ provides a mindmap library, drawing them is pretty easy:

• Define your styles
• Use the tree syntax for nesting nodes and children

I liked to produce this drawing:

And that’s the short code:

\documentclass{article}
\usepackage[landscape]{geometry}
\usepackage{tikz}
\usetikzlibrary{mindmap}
\usepackage{dtklogos}
\begin{document}
\begin{tikzpicture}
  \path [
    mindmap,
    text = white,
    level 1 concept/.append style =
      {font = \Large\bfseries, sibling angle = 90},
    level 2 concept/.append style =
      {font = \normalsize\bfseries},
    level 3 concept/.append style =
      {font = \small\bfseries},
    tex/.style     = {concept, ball color = blue,
      font = \Huge\bfseries},
    engines/.style = {concept, ball color = green!50!black},
    formats/.style = {concept, ball color = blue!50!black},
    systems/.style = {concept, ball color = red!90!black},
    editors/.style = {concept, ball color = orange!90!black}
  ]
  node  {\TeX} [clockwise from = 0]
    child[concept color = green!50!black, nodes = {engines}] {
      node {Engines} [clockwise from = 90]
        child { node {\TeX} }
        child { node {pdf\TeX} }
        child { node {\XeTeX} }
        child { node {Lua\TeX} }}
    child [concept color = blue, nodes = {formats}] {
      node {Formats} [clockwise from = 300]
        child { node {\LaTeX} }
        child { node {\ConTeXt} }}
    child [concept color = red, nodes = {systems}] {
      node {Systems} [clockwise from = 210]
        child { node {\TeX Live} [clockwise from = 300]
          child { node {Mac \TeX} }}
        child { node {MiK\TeX} [clockwise from = 60]
          child { node {Pro \TeX t} }}}
    child [concept color = orange, nodes = {editors}] {
      node {Editors} };
\end{tikzpicture}
\end{document}

If you get errors, ensure that the dtklogos and hologo package are installed, otherwise replace commands such as \ConTeXt by a simple word ConTeXt.
