Solución:
Los árboles TikZ probablemente serían el camino a seguir. Sin embargo, las cosas se ponen bastante complicadas desde el principio (ejemplo en Plain con XeTeX):
input tikz
fontfigfont="Myriad Pro" at 8pt
fonttinyfigfont="Myriad Pro" at 6pt
usetikzlibrary{trees,shapes.geometric}
tikzpicture[>=latex,font=figfont,lbl/.style={draw=black,very thin,fill=#1,ellipse}]
coordinate
child [grow=right] {
child {
child [grow=125] {
child [grow=left] {node {tinyfigfont Cost of Transport} edge from parent[<-,thin]}
child {
child [grow=left] {node {tinyfigfont Access to premises} edge from parent[<-,thin]}
child {node [lbl=yellow!20] {Transport}}
child [missing]
}
child [missing] edge from parent[<-,thick]
}
child [xshift=1cm] {
child [grow=125] {
child [grow=left] {node {tinyfigfont Security} edge from parent[<-,thin]}
child {node [lbl=green!20!yellow] {Premises}}
child [missing] edge from parent[<-,thick]
}
child
child [grow=-125]
}
child [grow=-125] {
child [grow=left] {node {tinyfigfont Consultation} edge from parent[<-,thin]}
child {node [lbl=purple!20] {Clients}}
child [missing] edge from parent[<-,thick]
}
}
};
endtikzpicture
bye
Esto podría mejorarse mucho, pero espero poder darte una idea.
Aquí hay una alternativa que usa pdflatex. Lo hice basándome en el ejemplo de https://texwelt.de/fragen/13171/ishikawa-tikz-diagram. Esta es básicamente una forma no iterativa de ese ejemplo con etiquetas de texto incluidas.
Código de látex:
documentclass[tikz]{standalone}
usetikzlibrary{arrows,shapes.geometric,positioning,matrix}
tikzset{
ishikawa/.style={align=center, inner sep=0pt},
matter/.style ={rectangle, minimum size=6mm, very thick, draw=red!70!black!40,
top color=white, bottom color=red!50!black!20, font=itshape},
level_1/.style ={ellipse, node distance=60pt, minimum size=6mm, very thick,
draw=red!50!black!50, top color=white, bottom color=red!50!black!20, font=itshape},
level_2/.style={rectangle, minimum size=6mm, font=itshape, font=scriptsize}}
tikzset{
rows/.style 2 args={@/.style={row ##1/.style={#2}},@/.list={#1}},
cols/.style 2 args={@/.style={column ##1/.style={#2}},@/.list={#1}},
}
begin{document}
