The graph canvas is the workspace where you create, edit, and run graphs.

During a graph run, all toolbar buttons are disabled. See Run a graph for details on the running state.
The Settings
button opens the Graph settings panel. It's in the top-right area of the canvas.
Use the view controls at the bottom center of the canvas to adjust the viewport:
Pan the canvas using the scroll wheel or by dragging. The viewport position and zoom level are stored per tab.
The Minimap in the bottom-right corner shows a scaled overview of the entire canvas and reflects the current viewport position.
