I want to be able to do this on the big graph, to view the entire thing in the background (with a minimap showing where I am). It’s a very different feeling. It’s like navigating your little universe of knowledge.
Imagine the big graph is faded. When I click on a node, it becomes highlighted.
When I click on another node, the new one becomes highlighted, and the previous one becomes faded, but more visible than the background.
I can thus see both where I came from and where I currently am at the same time. I can see my entire journey during that session at a glance.
