Graphics, Figures & Tables ⇒ Graph with nodes.

[Novermars]

Hello everybody!

For an assignment, I have to make a graph with 8 nodes and connect them. In the end, it should look something like this:

I found the TikZ-package to be useful, but still have some questions.
Currently, I have the following figure:

graph_zps0e33b37c.png (92.63 KiB) Viewed 7125 times

with the following code:

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=2cm,
  thin,main node/.style={circle,fill=blue!20,draw,font=\sffamily\Large\bfseries}]

  \node[main node] (1) {1};
  \node[main node] (2) [right of=1] {2};
  \node[main node] (3) [right of=2] {3};
  \node[main node] (4) [right of=3] {4};
  \node[main node] (5) [right of=4] {5};
  \node[main node] (6) [right of=5] {6};
  \node[main node] (7) [right of=6] {7};
  \node[main node] (8) [right of=7] {8};

  \path[every node/.style={font=\sffamily\small}]
    (1) edge node [right] {100} (2)
        edge [bend left] node[right] {180} (3)
        edge [bend left] node[right] {300} (4)
        edge [bend left] node[right] {380} (5)
        edge [bend left] node[right] {620} (6)
        edge [bend left] node[right] {950} (7)
        edge [bend left] node[right] {1140}(8)

    (2) edge node [right] {100} (3)
        edge [bend left] node[right] {180} (4)
        edge [bend left] node[right] {220} (5)
        edge [bend left] node[right] {400} (6)
        edge [bend left] node[right] {720} (7)
        edge [bend left] node[right] {820} (8)

    (3) edge node [right] {100} (4)
        edge [bend left] node[right] {140} (5)
        edge [bend left] node[right] {260} (6)
        edge [bend left] node[right] {480} (7)
        edge [bend left] node[right] {580} (8)
        
    (4) edge node [right] {100} (5)
        edge [bend left] node[right] {160} (6)
        edge [bend left] node[right] {300} (7)
        edge [bend left] node[right] {380} (8) 
     
    (5) edge node [right] {100} (6)  
        edge [bend left] node[right] {180} (7)
        edge [bend left] node[right] {220} (8)
        
    (6) edge node [right] {100} (7)   
        edge [bend left] node[right] {120} (8)
        
    (7) edge node [right] {100} (8);     
\end{tikzpicture}
\end{document}

And to make an understatement, it looks messy as hell. Is it possible to make it look more like the figure above, so more spacing between the lines and the numbers either above or below the line?

Thanks in advance!

Replace

Code: Select all

edge [bend left] node[right] {180} (3)

with

Code: Select all

edge [bend left=60] node[above] {180} (3)

That works wonderful, thank you!
