在python中如何抓取图表背后的数据？

import requests
from bs4 import BeautifulSoup

# 发送HTTP请求获取网页内容
url = 'https://example.com/chart'
response = requests.get(url)
html_content = response.text

# 使用BeautifulSoup解析网页内容
soup = BeautifulSoup(html_content, 'html.parser')

# 根据图表所在的HTML元素提取数据
chart_element = soup.find('div', class_='chart')
data_elements = chart_element.find_all('span', class_='data')

# 提取数据并打印
for data_element in data_elements:
    data = data_element.text
    print(data)
