What are some popular Python 3 libraries for data visualization?

Some popular Python 3 libraries for data visualization include Matplotlib, Seaborn, Plotly, and Bokeh.

Can you explain how to use Matplotlib for creating a simple line chart?

Sure! You can create a simple line chart using Matplotlib by importing the library and using the plot() function. Here's a basic example:

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [10, 20, 25, 30]

plt.plot(x, y)
plt.title('Simple Line Chart')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.show()

What about Seaborn? How is it different from Matplotlib?

Seaborn is built on top of Matplotlib and provides a high-level interface for drawing attractive statistical graphics. It simplifies the process of creating complex visualizations and comes with built-in themes and color palettes.

Can you give me an example of a heatmap using Seaborn?

Certainly! Here's a simple example of creating a heatmap using Seaborn:

import seaborn as sns
import matplotlib.pyplot as plt

# Sample data
data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

sns.heatmap(data, annot=True)
plt.title('Heatmap Example')
plt.show()
