the issue is that you can't create and pack your canvas at the same time. this should work:

from tkinter import *

root = Tk()
root.title("Sorting Algorithm Visualiser")
root.geometry("1500x780+0+0")
root.config(bg="#D7DBDD")

canvas = Canvas(root, width=1000, height=500, bg="#F8F9F9")

canvas.create_rectangle(50, 25, 150, 75, fill="red")

canvas.pack()

root.mainloop()
