tikz - how to bend straight lines in a graph

enter image description here

So I'm trying to plot a graph with routes. I have two questions:

How can I bend the lines? I would like the 9->4 to go around node 7.

How can I change the names of the nodes? I want node 9 to be called "0".

Is the method I chose to simple to make these changes?

begintikzpicture[scale=.1,vertex/.style=draw,circle, arc/.style=draw,thick,->]
foreach [count=i] coord in (40,30),(90,10),(20,70),(100,20),(90,20),(70,30),(70,40),(10,70),(50,50)
 node[vertex] (pi) at coord i;

foreach [count=r] row in 0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,1,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,1,0
 foreach [count=c] cell in row
 ifnumcell=1%
 draw[arc] (pr) edge (pc);
 fi
 
 
endtikzpicture

Welcome to TeX.SE! I had to rescale your coordinates to avoid dimension too large errors, yet the graph looks as if I had not done that.

begintikzpicture[vertex/.style=draw,circle, arc/.style=draw,thick,->]
foreach [count=i] coord in (4,3),(9,1),(2,7),(10,2),(9,2),(7,3),(7,4),(1,7),(5,5)
 ifnumi=9
 node[vertex,alias=p0] (pi) at coord 0;
 else
 node[vertex] (pi) at coord i;
 fi

foreach [count=r] row in 0,0,0,0,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,1,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,1,0

I coded your figure in a simpler way using the native possibilities of the foreach loop and the chains library.

It is possible to make only one loop: the one that defines the nodes. To make node 9 (5,5) named 0, simply place it at the beginning of the foreach and start the count at zero.

foreach coord [count=i from 0] in (5,5),(4,3),(9,1),(2,7),(10,2),(9,2),(7,3),(7,4),(1,7)
 node[vertex] (pi) at coord i;

Then with the chains library to connect the nodes with arrows.

documentclass[tikz,border=5mm]standalone
usetikzlibrarychains

begindocument

begintikzpicture[start chain,scale=1,vertex/.style=draw,circle, every join/.style=draw,thick,->]
foreach coord [count=i from 0] in (5,5),(4,3),(9,1),(2,7),(10,2),(9,2),(7,3),(7,4),(1,7)
 node[vertex] (pi) at coord i;


chainin (p0);
chainin (p8)[join];
chainin (p3)[join];
chainin (p1)[join];
chainin (p0)[join];
chainin (p4)[join=with p0 by bend left];
chainin (p2)[join];
chainin (p5)[join];
chainin (p6)[join];
chainin (p7)[join];
chainin (p0)[join];
