Graph Assistant and the AtomIQ MCP both say the workspace is empty

I opened Graph Assistant and an external client against the AtomIQ MCP. Both have nothing to say. What has to exist first?

Both read the workspace graph. Import the programs, let analysis build relationships, and save operations before you expect answers. Graph Assistant is the in-app chat over that graph. The MCP lets another assistant read and drive the same workspace. Neither one invents a graph from an empty workspace.
