I'm trying to make something akin to the below image in LaTeX. The closest I've come has been with the forest package, but it does not seem to certain desired capabilities — in particular, the arc around the three edges from the central node. Additionally, I cannot see how one would add the smaller edges below easily, however this is far less of a concern.

Are there any packages or tools available in LaTeX to help me design something similar? Or a way to do this with the forest package?

Example

The below is the closest I have gotten it. The lack of arrows is fine, it is fundamentally the arc which I'd like.

\documentclass[11pt,a4paper]{article}

\usepackage{forest}

\begin{document}

\tiny
\begin{forest}
for tree={
  draw,
  minimum height=1cm,
  anchor=north,
  align=center,
  child anchor=north
},
[{Get malicious code\\on the user device}, align=center, name=AD
  [{Bypass the appstore}]
  [{Exploit vulnerability in installed app}]
  [{Sell/distribute\\malicious app in\\appstore}
    [{Create malicious\\app}]
    [{Cicumvent app\\review}]
    [{Troll/falsify app\\reputation}]
  ]
]
\end{forest}
\end{document}

  • Welcome to TeX.se. Instead of just posting an image of what you want, could you add a minimal compilable document that shows what you're tried with forest? (Although be aware that this isn't a tree, since some nodes have multiple parents.) – Alan Munn Apr 8 '18 at 18:30
  • welcome to tex.se! what you try so far? locus you can draw with help of tikz library angles. – Zarko Apr 8 '18 at 18:31
  • Thanks for adding some code. Can you wrap it in a complete compilable document, though. – Alan Munn Apr 8 '18 at 21:50
  • I've added the closest I've managed, using forest. – Alex W Apr 8 '18 at 21:50
  • Yep, sure thing. (sorry!) – Alex W Apr 8 '18 at 21:50

Here I have a code that works using brute force, but it does not evade suffering, but it was only to be able to declare texts in circles in a simple way; whatever the package you are using I did not find it appropriate since it is oriented for other things, I think ... but as you know the path of tikz requires a lot of pain and suffering, but when you master it with the basics you can achieve everything ... Analyze the code is partially explained under the MIT licensing parameters, trying to make it as simple and structured so that it is understood without saving anything for oneself ...

All that paraphernalia to generate this ..., if someone can improve it, I will also be grateful.

Here's one way to add arcs to a Forest tree. If you want to do this without adjusting things for different cases, consider setting a common parent anchor for all children (e.g. parent anchor=children). Otherwise, the size of the nodes will require adjusting the arcs' radii and angles.

\documentclass[border=10pt]{standalone}
\usepackage{forest}
\forestset{%
  angle below/.style={
    tikz+={%
      \draw ($(!1.child anchor)!.35!(.parent anchor)$) [bend right=15] to ($(.parent anchor)!.65!(!l.child anchor)$);
    },
  },
}
\begin{document}

\begin{forest}
  for tree={
    draw,
    minimum height=1cm,
    anchor=parent,
    align=center,
    child anchor=parent
  },
  [{Get malicious code\\on the user device}, name=AD
    [{Bypass the appstore}]
    [{Exploit vulnerability in installed app}]
    [{Sell/distribute\\malicious app in\\appstore}, angle below
      [{Create malicious\\app}]
      [{Cicumvent app\\review}]
      [{Troll/falsify app\\reputation}]
    ]
  ]
\end{forest}
\end{document}
