如何在类函数中创建带有椭圆的花朵形状？

import matplotlib.pyplot as plt
from matplotlib.patches import Ellipse

class Flower:
    def __init__(self):
        self.fig, self.ax = plt.subplots()

    def draw_flower(self):
        # 绘制椭圆形状的花朵
        ellipse = Ellipse(xy=(0.5, 0.5), width=0.4, height=0.6, angle=45, facecolor='pink')
        self.ax.add_patch(ellipse)

        # 设置坐标轴范围
        self.ax.set_xlim(0, 1)
        self.ax.set_ylim(0, 1)

        # 隐藏坐标轴
        self.ax.axis('off')

        # 显示绘制结果
        plt.show()

flower = Flower()
flower.draw_flower()
