simple animation using tinter
===

I have a simple code to visualise some data using tkinter. A button click is bound to the function that redraws the next "frame" of data. However, I'd like to have the option to redraw automatically with a certain frequency. I'm very green when it comes to GUI programming (I don't have to do a lot for this code), so most of my tkinter knowledge comes from following and modifying examples. I guess I can use root.after to achieve this, but I'm not quite sure I understand how from other codes. The basic structure of my program is as follows:

    # class for simulation data
    # --------------------------------
    
    def Visualisation:

       def __init__(self, args):
           # sets up the object


       def update_canvas(self, Event):
           # draws the next frame

           canvas.delete(ALL)
          
           # draw some stuff
           canvas.create_........


    # gui section
    # ---------------------------------------

    # initialise the visualisation object
    vis = Visualisation(s, canvasWidth, canvasHeight)

    # Tkinter initialisation
    root = Tk()
    canvas = Canvas(root, width = canvasWidth, height = canvasHeight)

    # set mouse click to advance the simulation
    canvas.grid(column=0, row=0, sticky=(N, W, E, S))
    canvas.bind('<Button-1>', vis.update_canvas)

    # run the main loop
    root.mainloop()

Apologies for asking a question which I'm sure has an obvious and simple answer. Many thanks.
