Plot Settings
When interacting with a Network Graph in Explore, navigate to the Plot Settings in the Mapping panel dropdown menu to customize your visualizations. You may toggle points, designate Edge Curvature, and choose to toggle edges or simply show a sample of them.
Appearance Settings
There are several options available in the Appearance section of the Settings window to adjust the Default Edge Color, Default Maps Edge Color, Default Edge Insight Color and Edge Alpha, for both Desktop and VR. The Edge Alpha adjusts the opacity of the edges to make them bolder or fainter.
