Update graph styles

- Increase item height to 30px - Increase icon size to 20px - Update colours of edges, arrows, and default text / outlines - Update spacing of elements in node labels - Avoid duplicating the marker (arrow) definition - Update arrow definition to produce a cleaner shape when zoomed - Set fixed width for nodes at 200px - Switch to center truncation on long labels
