在Tkinter中有没有办法标记一个椭圆(canvas.create_oval)？

import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(root, width=400, height=400)
canvas.pack()

# 绘制椭圆
oval = canvas.create_oval(100, 100, 300, 200, fill="red")

# 获取椭圆的中心点坐标
x1, y1, x2, y2 = canvas.coords(oval)
center_x = (x1 + x2) / 2
center_y = (y1 + y2) / 2

# 在椭圆中心点添加标签
label = canvas.create_text(center_x, center_y, text="椭圆", fill="white")

root.mainloop()
