What are some effective data visualization techniques in Python?

There are several effective techniques, including line charts, bar charts, scatter plots, and heatmaps. Do you have a specific dataset in mind?

I'm working with a sales dataset. Which visualization would be best for showing trends over time?

For showing trends over time, a line chart is usually the best choice. It clearly displays changes in data points over a continuous interval.

How can I create a line chart using Matplotlib?

You can create a line chart using Matplotlib by importing the library and using the plot() function. Would you like a code example?

Yes, please provide a simple code example.

Sure! Here's a basic example:

import matplotlib.pyplot as plt

dates = ['2021-01', '2021-02', '2021-03']
sales = [200, 300, 250]

plt.plot(dates, sales)
plt.title('Sales Trends Over Time')
plt.xlabel('Date')
plt.ylabel('Sales')
plt.show()
