GD 2004 Contest Rules

The graph drawing contest has two distinct tracks: the graph drawing challenge and the freestyle contest. To view the detailed rules for the GD 2004 Graph Drawing Contest, please click here.

Here is a brief overview of the graph drawing challenge:


Graph Format

For the GD2004 contest, we will use a modified ASCII format described below. The contest graphs will be provided in this format and the submission should be prepared using the same format.

Sample File

Below is a simple example:
-----------------------------------------------------------------
# Lines starting with # are comments and ignored
# First value is NumNodes(N)
4
# Next N pairs are X,Y (double) coordinate values of each node 0,1, N-1
0.0 0.0 # Node 0
0.0 5.0 # Node 1
5.0 5.0 # Node 2
5.0 0.0 # Node 4
# Remaining pairs of INTEGER values are undirected edges Ns, Ne
0 1 # Edge from Node 0 to Node 1
0 2
0 3
1 2
1 3
2 3

# Here we defined a 4-clique (with 1 crossing)
