Demo 3 should not display expression data on nodes #1276
Description
The intention behind demo 3 is that it does not display expression data on the nodes (see documentation webpage). I'm not sure when this changed, but we need to make it do that again. So demo 3 should default to node coloring turned off.
We don't store the Schade data as one of our options in the expression database because it's not a fully public dataset. We only had permission to share the expression data for the genes in the demo network.
