Visualizing survey data
Following up on the previous exercise on survey data among European IT specialists, visualize the linear relationship between experience_years and current_salary, to give a rough estimate of what different levels of experiences are earning.
The data has been loaded for you as data, along with pandas, Matplotlib.pyplot, and NumPy, as pd, plt, and np, respectively.
