y = 2*x + 1 + np.random.randn(50)

plt.figure(figsize=(8, 6))
plt.scatter(x, y, marker='o', s=50, c='blue', label='Data Points')
plt.plot(x, 2*x + 1, 'r-', label='Linear Regression')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Scatter Plot with Regression Line')
plt.legend()
plt.grid(True)
plt.savefig("matplotlib_plot.png") # Save as static image
plt.show()

Harnessing Plotly’s Interactivity:

Plotly, on the other hand, excels in creating interactive visualizations.
