Icome Clasification
The main objective of the code is to perform exploratory data analysis, specifically visualizing the distribution of occupations among individuals with incomes above 50K.

To achieve this, the code first loads and prepares the data, including checking for null values and renaming the columns for easier manipulation. Then, the three most common occupations among individuals with incomes above 50K are selected. Finally, a stacked bar chart is created to visualize the distribution of occupations by income level, providing a clear and concise representation of this information.
This analysis and visualization are useful in several ways. On one hand, it helps understand which occupations are more prevalent in the higher income group, which could be valuable for various analyses and decision-making in areas such as economics, labor policies, education, and more. On the other hand, the data cleaning and preparation process demonstrates good practices in data handling that can be applied to other datasets and analysis problems.
