使用Python的Matplotlib库

```python

import matplotlib.pyplot as plt

import numpy as np

t = np.linspace(0, 2 * np.pi, 1000)

x = 20 * np.sin(t)3

y = 13 * np.cos(t) - 5 * np.cos(2 * t) - 2 * np.cos(3 * t) - np.cos(4 * t)

plt.plot(x, y, color='red')

ax = plt.gca()

ax.fill(x, y, 'red', alpha=0.3)

plt.axis('equal')

plt.axis('off')

plt.show()

```

使用Python的turtle库

```python

import turtle

turtle.color('red')

turtle.pensize(3)

绘制下半部分的爱心

turtle.begin_fill()

turtle.left(50)

turtle.forward(133)

turtle.circle(50, 200)

turtle.right(140)

turtle.circle(50, 200)

turtle.forward(133)

turtle.end_fill()

绘制上半部分的爱心

turtle.left(140)

turtle.up()

turtle.fd(280)

turtle.left(140)

turtle.down()

turtle.begin_fill()

turtle.circle(111, 200)

turtle.right(120)

turtle.circle(111, 200)

turtle.end_fill()

隐藏画笔

turtle.hideturtle()

turtle.done()

```

使用JavaScript和HTML5 Canvas
