QuickGraph and GraphLight are both excellent!

Quick Graph(http://quickgraph.codeplex.com) is a generic Graph Data Structures and Algorithms for .NET (support SL; without supporting Layout).

I'm now using the two framework in my work. There are some things that can be optimized:

1. The graphviz parser in GraphLight.

(1) If there is no "nodes:" and "edges:" in data file , parser errors will occur:

digraph G {
0 ;
1 ;
2 ;
3 ;
4 ;
5 ;
6 ;
7 ;
8 ;
9 ;
0 -> 1 [];
0 -> 2 [];
0 -> 3 [];
0 -> 4 [];
0 -> 5 [];
0 -> 6 [];
0 -> 7 [];
0 -> 8 [];
0 -> 9 [];
}

QuickGraph can output this kind of data. I don't know whether it fit the graphviz standards...

(2)  I tried to update outputing format. parser errors also occured.

digraph G {
center=true
0 [label="RDF评论词汇表"];
1 [label="评论", tooltip="对一项事物的评论。"];
2 [label="注释", tooltip="关于一个评论的注释。"];
3 [label="反馈", tooltip="对评论的反馈，表达了这条评论是否有用。"];
4 [label="评级", tooltip="一个数值。"];
5 [label="文本", tooltip="评论的文本。"];
6 [label="有评论", tooltip="关联一个事物和一条评论。"];
7 [label="评论者", tooltip="撰写评论的人。"];
8 [label="最小评级", tooltip="一个数值"];
9 [label="最大评级", tooltip="一个数值"];
0 -> 1 [ comment="RelatedClass"];
0 -> 2 [ comment="RelatedClass"];
0 -> 3 [ comment="RelatedClass"];
0 -> 4 [ comment="Property"];
0 -> 5 [ comment="Property"];
0 -> 6 [ comment="Property"];
0 -> 7 [ comment="Property"];
0 -> 8 [ comment="Property"];
0 -> 9 [ comment="Property"];
}

I think the problem is GRAPH() in MyParser class. Between NODES() and EDGES(), there maybe are some graph attributes that should be processed. ^0^

2  QuickGraph.Collectios and QuickGraph.Collections can integrated together.

3 I integrated the two frameworks using a lazy and dirty method:

public static DrawingGraph Convert( LoreSchemaGraph g, string graphLabel )

 OK. Like the data i listed above. If there is one core node and many different nodes linked to it. Then the rendered result will be:

                                      N0

N1  N2  N3  N4  N5  N6  N7  N8  N9  N10   N11  N12   N13

I  leave out the edges in the example. If the graph has many linked nodes, the graph will be very ugly.

The algorithm should be like a circle?

           N1  N2  N3  N4

        N5        N0       N6

 N7                                 N13

    N8  N9  N10   N11  N12
