I am working in a research project where I deal with rooted trees.
I want to be able to add edges to the rooted tree and somehow "preserve" the rooted tree layout. More precisely, if I add the edges $(2,8)$ and $(3,6)$ in the rooted tree produced by the code below
G=Graph({0:[1,2,3,4],1:[5,6,7],4:[8,9,10],6:[11,12],9:[13,14]})
G.show(layout='tree',tree_root=0)
G.add_edges([(3,9),(2,6)])
G.show()
the layout of the updated graph is kind of messy and it gets worse if the order of the tree is increased. I want to add the new edges in a different color but without affecting the layout of the initial tree. I want the updated graph to look like the output of this tikzpicture:
\begin{tikzpicture}[
V/.style = {% V as Vortex
circle,thick,fill=orange},scale=0.4]
%drawing nodes
\node[V] (0) at (-9,11) [scale=0.5,draw] {0};
\node[V] (1) at (-3,8) [scale=0.5,draw] {1};
\node[V] (2) at (-7,8) [scale=0.5,draw] {2};
\node[V] (3) at (-11,8)[scale=0.5,,draw] {3};
\node[V] (4) at (-15,8) [scale=0.5,draw] {4};
\node[V] (5) at (-1,5) [scale=0.5,draw] {5};
\node[V] (6) at (-3,5) [scale=0.5,draw] {6};
\node[V] (7) at (-5,5) [scale=0.5,draw] {7};
\node[V] (8) at (-13,5) [scale=0.5,draw] {8};
\node[V] (9) at (-15,5) [scale=0.5,draw] {9};
\node[V] (10) at (-17,5) [scale=0.4,draw] {10};
\node[V] (11) at (-2,2) [scale=0.4,draw] {11};
\node[V] (12) at (-4,2) [scale=0.4,draw] {12};
\node[V] (13) at (-14,2) [scale=0.4,draw] {13};
\node[V] (14) at (-16,2) [scale=0.4,draw] {14};
\draw[black,very thick]
(0) to (1)
(0) to (2)
(0) to (3)
(0) to (4)
(1) to (5)
(1) to (6)
(1) to (7)
(6) to (11)
(6) to (12)
(4) to (8)
(4) to (9)
(4) to (10)
(9) to (13)
(9) to (14);
\draw[green,very thick,dotted]
(3) to (9)
(2) to (6);
\end{tikzpicture}
Is this even possible? possible?
