How can I control node label font size of a graph or digraph object?

I want to plot a graph or digraph (R2015b). Unfortunately, the node labels are barely legible because the font size is too small.
How can I change the font size of the node labels?
My example code is from the Matlab documentation:
s = {'a' 'a' 'a' 'b' 'b' 'c' 'd' 'd' 'd'};
t = {'b' 'c' 'd' 'd' 'a' 'b' 'c' 'a' 'b'};
G = digraph(s,t);
labels = {'a/3' 'a/3' 'a/3' 'b/2' 'b/2' 'c' 'd/3' 'd/3' 'd/3'};
p = plot(G,'Layout','layered','EdgeLabel',labels);
highlight(p,[1 1 1],[2 3 4],'EdgeColor','g')
highlight(p,[2 2],[1 4],'EdgeColor','r')
highlight(p,3,2,'EdgeColor','m')
title('Page Rank Score Transfer Between Nodes')
I would expect p to have a property "NodeLabelFontSize" (or similar), but there is no property to control label appearance.
% get properties of p
get(p)

I'm curious to know how this could be modified to change the font size of the edge labels. Using a symmetric matrix A corresponding to a weighted, undirected network, I have
G=graph(A);
plot(G,'EdgeLabel',G.Edges.Weight)

Hi Jakob,
I looked into this and it appears that there currently isn't a way to change the font size of the labels of a graph.

You can customize node and edge labels with font properties, including NodeFontSize and EdgeFontSize, as of release R2018b.

any word on this? not only is it crazy that the graph label size can't be changed, but the default size is tiny!

s = [1 1 1 2 2 3 3 4 5 5 6 7 7 8 8 9 10 11];
t = [2 3 10 4 12 4 5 6 6 7 9 8 10 9 11 12 11 12];
G = digraph(s,t)
plot(G,'Layout','force','EdgeColor',"#0072BD",'NodeColor', "#D95319",'NodeFontSize',15,'NodeFontWeight','bold')
