Hi @saiavinash663, Great question! 😊 To run and view data visualizations with Matplotlib, ensure you've imported Matplotlib in your script and added the required plotting commands. After writing your code, run the script in your Python environment, and the plots should appear. For example (Python Code): import matplotlib.pyplot as plt x = [1, 2, 3, 4] y = [10, 20, 25, 30] plt.plot(x, y) plt.title('Sample Plot') plt.show() ============================================ Let me know if you'd like a detailed video on Matplotlib visualizations, and consider subscribing for more helpful content! 🚀"

Hi @TimKiefer-s7k, apologies for the delayed response! The error you’re encountering (SSLError with certificate verify failed) happens when there’s an issue with SSL certificate verification while connecting to PyPI. Here are some steps you can take to resolve this issue on your macOS system: 1️⃣ Upgrade pip First, upgrade pip to ensure you have the latest version: python3 -m pip install --upgrade pip If you get the same SSL error during this step, proceed to the next step. 2️⃣ Install or Update certifi The certifi package provides updated SSL certificates. Install or update it: python3 -m pip install --upgrade certifi 3️⃣ Set Python to Use the Correct Certificates macOS uses its own certificates, which can sometimes cause conflicts. Use the 'Install Certificates.command' script included with Python: -> Locate your Python installation folder. For example: /Applications/Python\ 3.x/ -> Run the script: open "/Applications/Python 3.x/Install Certificates.command" 4️⃣ Try Installing Matplotlib Again Now retry the installation as shown in the tutorial. 5️⃣ Check Your Network or Firewall Settings Sometimes, network proxies or firewalls can interfere with SSL verification. If you’re behind a corporate network, try connecting to a different network. If these steps don’t resolve the issue, please share any new error messages or updates so I can assist further. Also, if you’ve already resolved the problem in the meantime, it would be great if you could share how you fixed it to help others who might face a similar issue. 😊
After writing code, how to run data visualization as matplotlib
Hi @saiavinash663,
Great question! 😊 To run and view data visualizations with Matplotlib, ensure you've imported Matplotlib in your script and added the required plotting commands. After writing your code, run the script in your Python environment, and the plots should appear.
For example (Python Code):
import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 20, 25, 30]
plt.plot(x, y)
plt.title('Sample Plot')
plt.show()
