[Tex/LaTex] Venn Diagram using tikz

tikz-pgfvenn-diagrams

EDIT::
I saw the question mentioned in here which the moderator considered mine duplicate. However, I couldn't see how mine is duplicate. My main problem is to write the text in the intersection of CAT B and CAT C.

I am trying to create the following Venn diagram.

Following is my code and output:

\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture}
\begin{scope}[blend group = soft light]
\fill[red!30!white]   ( 90:1.2) circle (2);
\fill[green!30!white] (210:1.2) circle (2);
\fill[blue!30!white]  (330:1.2) circle (2);
\end{scope}
\node at ( 90:2)    {CAT A};
\node at ( 210:2)   {CAT B};
\node at ( 330:2)   {CAT C};
\node [font=\small] {text1, text2, text3, text4};
\end{tikzpicture}
\end{document}

I provide two examples. The first has a different layout compared to what you posted because I recycled something I had done previously. The second example uses the venndiagram package.

This is the code:

\documentclass[tikz,border=2pt,multi]{standalone}
\usepackage{venndiagram}

\tikzset{venn circle/.style={draw=gray,text opacity=1,fill opacity=0.25,circle,minimum width=10cm,fill=#1,line width=2pt}}
\tikzset{label/.style={text width=1.5cm,font=\large\sffamily}}

\begin{document}

\begin{tikzpicture}
    \begin{scope}[blend mode=screen]
          \node [venn circle = yellow] (A) at (0,0) {};
          \node [label] (A1) at (-2.5,0) {Cat A};
%
          \node [venn circle = green] (B) at (5,0) {};
          \node [label] (B1) at (7.5,0) {Cat B};  
%             
          \node [venn circle = orange] (C) at (2.5,5) {};
          \node [label] (C1) at (2.5,6.25) {Cat C};
% Use a tabular to stack the text
          \node [label] (D) at (5,3.75){\begin{tabular}{l} text1,\\text2,\\text3,\\text4 \end{tabular}};
        \end{scope}
\end{tikzpicture}

\begin{venndiagram3sets}[radius=5cm,overlap=3cm,
                         tikzoptions={text opacity=1,fill opacity=0.25},
                         labelOnlyBC={\begin{tabular}{l} text1,\\text2,\\text3,\\text4 \end{tabular}}]
   \fillBCapCNotA 
\end{venndiagram3sets}

\end{document}

This is the result:

A simple solution is

\documentclass{article}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
  \tikzset{venn circle/.style={draw,circle,minimum width=6cm,fill=#1,opacity=0.4}}

  \node [venn circle = red] (A) at (0,0) {$A$};
  \node [venn circle = blue] (B) at (60:4cm) {$B$};
  \node [venn circle = green] (C) at (0:4cm) {$C$};
  \node[left] at (barycentric cs:A=1/2,B=1/2 ) {$A \cap B$}; 
  \node[below] at (barycentric cs:A=1/2,C=1/2 ) {$A \cap C$};   
  \node[right] at (barycentric cs:B=1/2,C=1/2 ) {$B \cap C$};   
  \node[below] at (barycentric cs:A=1/3,B=1/3,C=1/3 ){$A \cap B \cap C$};
\end{tikzpicture}  
\end{document}

If you are looking to put the figures side by side, you can use several methods. Like a table, or just moving them with a subfloat, or using minipages. The main idea is that you need to wrap your diagrams, and them adjust the alignment of the wrappers.

For example, using subfloat, you can get:

\documentclass{article}

\usepackage{tikz}
\usepackage{subfig}

\begin{document}
% Definition of circles
\def\firstcircle{(0,0) circle (1.5cm)}
\def\secondcircle{(0:2cm) circle (1.5cm)}

\colorlet{circle edge}{blue!50}
\colorlet{circle area}{blue!20}

\tikzset{filled/.style={fill=circle area, draw=circle edge, thick},
outline/.style={draw=circle edge, thick}}

\setlength{\parskip}{5mm}
\begin{figure}
\centering
% Set A and B
\subfloat{%
\begin{tikzpicture}
\begin{scope}
    \clip \firstcircle;
    \fill[filled] \secondcircle;
\end{scope}
\draw[outline] \firstcircle node {$A$};
\draw[outline] \secondcircle node {$B$};
\node[anchor=south] at (current bounding box.north) {$A \cap B$};
\end{tikzpicture}
}
\hfil
%Set A or B but not (A and B) also known as A or B
\subfloat{%
\begin{tikzpicture}
\draw[filled, even odd rule] \firstcircle node {$A$}
                             \secondcircle node{$B$};
\node[anchor=south] at (current bounding box.north) {${(A \cap B)^{C}}$};
\end{tikzpicture}
}
\end{figure}

\end{document}

And again, you can do the same using a minipage, in which you have to indicate the width.

\documentclass{article}

\usepackage{tikz}

\begin{document}
% Definition of circles
\def\firstcircle{(0,0) circle (1.5cm)}
\def\secondcircle{(0:2cm) circle (1.5cm)}

\colorlet{circle edge}{blue!50}
\colorlet{circle area}{blue!20}

\tikzset{filled/.style={fill=circle area, draw=circle edge, thick},
outline/.style={draw=circle edge, thick}}

\setlength{\parskip}{5mm}
\begin{figure}
\centering
% Set A and B
\begin{minipage}{0.49\textwidth}
\begin{tikzpicture}
\begin{scope}
    \clip \firstcircle;
    \fill[filled] \secondcircle;
\end{scope}
\draw[outline] \firstcircle node {$A$};
\draw[outline] \secondcircle node {$B$};
\node[anchor=south] at (current bounding box.north) {$A \cap B$};
\end{tikzpicture}
\end{minipage}
%Set A or B but not (A and B) also known as A or B
\begin{minipage}{0.49\textwidth}
\begin{tikzpicture}
\draw[filled, even odd rule] \firstcircle node {$A$}
                             \secondcircle node{$B$};
\node[anchor=south] at (current bounding box.north) {${(A \cap B)^{C}}$};
\end{tikzpicture}
\end{minipage}
\end{figure}

\end{document}
