   rgraph = rgraph.resize((200,250),Image.ANTIALIAS)

You need to load the image first, resize it, then cast it into ImageTk.PhotoImage . Here is a working example that goes like so:

import tkinter as tk
from PIL import Image, ImageTk

x = tk.Tk()

# 1. load image
image = Image.open("risinggrap.jpg")

# 2. resize it
image = image.resize((200, 250), Image.ANTIALIAS)

# 3. cast it into ImageTk.PhotoImage
rgraph = ImageTk.PhotoImage(image)

photoLabel = tk.Label(x, image = rgraph)
photoLabel.pack(side = "bottom", fill = "both", expand = "yes")
x.mainloop()
