Question

I’m working with quite large graphs in notebook (I’m not a Mathematica expert).

Every time I load or manipulate a graph with instructions like these:

g = Import["out.graphml", "Graph"] or
g = VertexAdd[g, "aux"]

the graph is displayed in the result but the rendering is very very slow.

Is there a way to disable graph rendering in notebook?

Answer 1

The graphical portion of any Mathematica output can be suppressed by placing a semicolon at the end of the line.

g = Import["out.graphml", "Graph"];
g = VertexAdd(g, "aux");
