Data Visualization with Matplotlib
Build clear line, bar, and scatter plots with Matplotlib for reports and dashboards.
A picture is worth a thousand rows.
A simple line plot
import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [10, 14, 12, 18]
plt.plot(x, y, marker="o")
plt.title("Trend")
plt.xlabel("Day")
plt.ylabel("Value")
plt.show()Tips for readable charts
- Always label axes and add a title.
- Use
plt.tight_layout()before saving to avoid clipping. - Prefer fewer, clearer series over crowded plots.
