1 Creating graphs

There are two different ways to create graphs. You can choose to draw the knots and edges or you can specify the distances between knots in a matrix. Feel free to use them both!
All graphs are asymetric, so you have to specify two edges if the connection is bidirectional. A convienient way to create symetric test-graphs is to draw knots and choose Menu - Edges - create Edges - Knot 2 Knot graphical distance.
By the way, if you don't like the colors, press the right mouse button inside the drawing area...
