Hola a todos, quisiera saber si me pueden dar una sugerencia de como sombrear los circulitos, aquí les dejo el código
[cells={nodes={draw=black, ellipse}}]
&& v_3 \arrow["a_3"', no head, loop, distance=2em, in=125, out=55, color={rgb,255:red,92;green,92;blue,214} ] \arrow["{a_1}", color={rgb,255:red,92;green,92;blue,214}, no head, from=2-1, to=1-3] \\
{v_1} &&&& {v_5} \\
& {v_2} && {v_4}
\arrow["{a_1}", color={rgb,255:red,92;green,92;blue,214}, no head, from=2-1, to=1-3]
\arrow["{a_2}"', color={rgb,255:red,92;green,92;blue,214}, no head, from=2-1, to=3-2]
\arrow["{a_4}"', color={rgb,255:red,92;green,92;blue,214}, no head, from=3-2, to=3-4]
\end{tikzcd}\]
Gracias
