Research direction

Start by reproducing the graph viewer in VS Code with a small three-node graph, then zoom and pan to compare the rendered area with the surrounding pane. Trace the graph viewer entry point and viewport handling, using the attached screenshot and issue description as the expected behavior; done means the graph can use the full pane while zooming and panning.
