I want to create this tree that each node have its own shape. for example each nodes be circle and leaves be square. enter image description here

this code perfectly work but I want to use tree in my code.

    \matrix [column sep=1cm, row sep=1cm] {
        & & \node (in) [draw, shape=circle] {Income}; \\
        \node (lo) [draw, shape=rectangle, minimum size=1cm]    {Loan}; & &
        \node (ms) [draw, shape=circle] {MS}; & & &
        \node (cr) [draw, shape=circle] {CR}; \\
        & \node (lo2) [draw, shape=rectangle, minimum size=1cm] {Loan}; & &
        \node (noLoan) [draw, shape=rectangle, minimum size=1cm] {No loan}; &
        \node (lo3) [draw, shape=rectangle, minimum size=1cm] {Loan}; & &
        \node (noLoan2) [draw, shape=rectangle, minimum size=1cm] {No loan};\\
    \draw[->] (in) -- (lo);
    \draw[->] (in) -- (ms);
    \draw[->] (in) -- (cr);
    \draw[->] (ms) -- (lo2);
    \draw[->] (ms) -- (noLoan);
    \draw[->] (cr) -- (lo3);
    \draw[->] (cr) -- (noLoan2);

  • @Zarko Thanks. couldn't write code here so I edit the question. Commented Dec 2, 2023 at 11:08
  • That is right that you edit your question. Now all can see your effort and will see, where you stuck. I will try to help you latter afternoon ...

Drawing as tree by use of the forest package. A wee bit sophisticated but short code:

\usepackage{forest} % it load tikz too

for tree =  {
% nodes styles
        minimum size=3em,
        inner sep=2pt,
  where level = 2{}{circle, draw},
        align = center,
       anchor = north,
       %child anchor=north,
% tree style
         edge = {-Straight Barb, semithick},
        s sep = 12 mm,
        l sep = 16 mm,
  where level = 1{s sep=2mm}{},
% edge labels
EL/.style 2 args = {edge label={%
                    node[midway, font=\footnotesize, align=center,
                         inner sep=2pt, anchor=south #1]{#2}},
    [loan, rectangle, EL={east}{high}]
    [MS, EL={east}{medium}, 
         before computing xy={s/.average={s}{siblings}}
        [loan, EL={east}{maried}] 
        [no\\ loan, EL={west}{no\\ married}]   
    [CR, EL={west}{low},
        [loan, EL={east}{good}] 
        [no\\ loan, EL={west}{poor}]   

enter image description here

  • Thanks, that was great but is there any way to use tree easier? Commented Dec 2, 2023 at 16:14
  • @ErfanRiahi, what you mean with "easier"? Code is simple, concise and relative easy to understand (regardless that I said that it is sophisticated ;-), this I mean in comparison to your codein question.

  • You don't need where inside for tree - you just add additional processing. It's more efficient to use if or to take the where outside the for tree. The same goes for the style definition. You don't need to define for each node individually ;).

  • See chat.stackexchange.com/transcript/message/64801439#64801439. @ErfanRiahi You asked for a tree. forest provides one fairly straightforward way to create a tree. If this isn't what you wanted, can you clarify what you do want?

  • @cfr No, it's ok. thanks. another question: how can I use this tree in beamer? and is it possible to use pause for each node? Commented Dec 3, 2023 at 6:05
