    Summary:
     The graph can be zoomed in and zoomed out.

    Expected Behavior:
     The graph is zoomed in when when we click View->ZoomIn
     The graph is zoomed out when when we click View->ZoomOut

    Test Steps:
     1) Open Script Canvas window (Tools > Script Canvas)
     2) Get the SC window object
     3) Create new graph
     4) Get initial graph transform values
     5) Trigger Zoom In and verify if the graph transform scale is increased
     6) Trigger Zoom Out and verify if the graph transform scale is decreased
     7) Close Script Canvas window
