Two-set and three-set diagrams: venndiagram package

Question

I just wanted to know if there are any packages that build two or three intersecting sets, where you can put a number inside them, a capital letter on the set and with the universe set indicated a capital letter. Thank you.

See the example below.

I have these two MWE:

\documentclass[a4paper,12pt]{article}
\usepackage{mathtools,amssymb,venndiagram}
\begin{document}
\begin{venndiagram3sets}[labelOnlyA={1},labelOnlyB={2},labelOnlyC={3},
labelOnlyAB={4},labelOnlyAC={5},labelOnlyBC={6},labelABC={7},
labelNotABC={8}]
\end{venndiagram3sets}
\end{document}

The code with 2 sets not work well if I write labelOnlyAB={4}. In fact the 4 is missing in the A∩B. It is necessary to write labelAB={4} instead of labelOnlyAB={4}.

\documentclass[a4paper,12pt]{article}
\usepackage{mathtools,amssymb,venndiagram}
\begin{document}
\begin{venndiagram2sets}[labelOnlyA={5},labelOnlyB={7}, labelAB={4},labelNotAB={15}]
\end{venndiagram2sets}
\end{document}

How can I put the set U outside the rectangle and upper right above the rectangle?

looks like nothing apart from TikZ. — user202729, Oct 15 '23 at 12:12
You can use https://ctan.org/pkg/venndiagram, when you allow circles. It's built on Tikz, so you can add labels, lines etc. easily. — MS-SPO, Oct 15 '23 at 12:16
@MS-SPO Thank you very much. The problem is that sets cannot be colored with venndiagram. — Sebastiano, Oct 15 '23 at 12:17
@Sebastiano, right, the manual isn‘t verbose about this. But see here, as it‘s still tikzish: https://tex.stackexchange.com/a/661252/245790. — MS-SPO, Oct 15 '23 at 13:36
The answers to Q67395 cover all possible 3-sets. And Q266326 is about the 2-sets. — Qrrbrbirlbel, Oct 15 '23 at 14:46
labelOnlyAB is a 3-set only key as per the manual. You can use \setpostvennhook{\node[below right]at(venn bottom left){$U$};} to add further TikZ code to the diagram. — Qrrbrbirlbel, Oct 16 '23 at 22:46
@Qrrbrbirlbel Using \documentclass[a4paper,12pt]{article} \usepackage{mathtools,amssymb,venndiagram,tikz} \begin{document} \begin{venndiagram2sets}[labelOnlyA={5},labelOnlyB={7}, labelAB={4},labelNotAB={15}] \setpostvennhook{\node[above right]at(venn bottom right){$|U|=50$};} \end{venndiagram2sets} \end{document} I have not $|U|=50$ at top right above the rectangle. — Sebastiano, Oct 17 '23 at 07:48
See page 6 and Ex. 6 on page 8 in the manual about \setpostvennhook, i.e. relate to venn top left if I don't get it wrong. https://mirror.dogado.de/tex-archive/macros/latex/contrib/venndiagram/venndiagram.pdf . Results: see the example doc: https://ctan.mirror.norbert-ruehl.de/macros/latex/contrib/venndiagram/samples/venn-sample.pdf — MS-SPO, Oct 17 '23 at 08:34
@Sebastiano Looks good to me.. venn bottom right is obviously the bottom right corner, above right (= anchor = south west) just specifies the nodes placement in relation to the at place. Use venn top right instead. (Unfortunately, the rectangle is not a node, the package just defines coordinates for the four corners.) — Qrrbrbirlbel, Oct 17 '23 at 08:47
@Qrrbrbirlbel Perfect!!!! Thank you very vey very very much. I give me a downvote. I not know the reason. — Sebastiano, Oct 17 '23 at 10:48

By the comments of @Qrrbrbirlbel user I have found the correct aspect.

\documentclass[a4paper,12pt]{article}
\usepackage{mathtools,amssymb,venndiagram,tikz} 
\begin{document} 
\begin{venndiagram2sets}[labelOnlyA={5},labelOnlyB={7}, labelAB={4},labelNotAB={15}] 
\setpostvennhook{\node[above right] at (venn top right){$|U|=50$};}
\end{venndiagram2sets} 
\end{document}

\documentclass[a4paper,12pt]{article}
\usepackage{mathtools,amssymb,venndiagram}
\begin{document}
\begin{venndiagram3sets}[labelOnlyA={1},labelOnlyB={2},labelOnlyC={3},
labelOnlyAB={4},labelOnlyAC={5},labelOnlyBC={6},labelABC={7},
labelNotABC={8}]
\setpostvennhook{\node[above right] at (venn top right){$|U|=30$};}
\end{venndiagram3sets}
\end{document}
