# nodes inside an ellipse

I would like to draw nodes inside those two ellipses(and then draw edges).I would also like some of the vertices to be within another elipse The code is

\begin {center}
\begin {tikzpicture}
\tikz
\draw (5,0) ellipse (4cm and 0.5cm);
\end{tikzpicture}
\end {center}
\begin {center}
\begin{tikzpicture}
\tikz \draw (5,0) ellipse (4cm and 0.5cm);
\end{tikzpicture}
\end {center}

• You don't need \tikz, you already have the tikzpicture environment. Please post compilable code and clarify what you want to achieve. You can use some mock-up picture for this. – Alenanno Mar 18 '16 at 17:31
• I will trie without \tikz, seems that i can draw vertices in this way inside the elipse.I will also try to ordinate another elipse inside – Jac Mar 18 '16 at 17:50
