Introduction

A circle graph, also known as a pie chart, is a type of graph that displays how different categories contribute to a whole. It is a useful tool for visualizing data and making it easier to understand complex information. In this article, we will create a circle graph for the highest federal salaries in the United States, using the data provided.

Understanding the Data

The data provided shows the highest federal salaries in the United States, with the President and Vice President being the two highest-paid positions. The salaries are in thousands of dollars.

Position	Salary (in thousands of dollars)
President	$400.0
Vice President	$

Calculating the Percentage of Each Category

To create a circle graph, we need to calculate the percentage of each category. We will use the following formula:

Percentage = (Salary / Total Salary) x 100

We will assume that the total salary is the sum of the salaries of the President and Vice President.

Calculating the Total Salary

Let's calculate the total salary:

Total Salary = President's Salary + Vice President's Salary Total Salary = $400.0 + $ (assuming the Vice President's salary is x)

We need to find the value of x. Since the Vice President's salary is not provided, we will assume that it is less than the President's salary. Let's assume that the Vice President's salary is $300.0.

Total Salary = $400.0 + $300.0 Total Salary = $700.0

Calculating the Percentage of Each Category

Now that we have the total salary, we can calculate the percentage of each category:

President's Percentage = (President's Salary / Total Salary) x 100 President's Percentage = ($400.0 / $700.0) x 100 President's Percentage = 57.14%

Vice President's Percentage = (Vice President's Salary / Total Salary) x 100 Vice President's Percentage = ($300.0 / $700.0) x 100 Vice President's Percentage = 42.86%

Creating the Circle Graph

Now that we have the percentages, we can create the circle graph. We will use a pie chart to display the data.

Circle Graph Code

Here is the code to create the circle graph:

import matplotlib.pyplot as plt
labels = ['President', 'Vice President']
sizes = [57.14, 42.86]
plt.pie(sizes, labels=labels, autopct='%1.1f%%')
plt.axis('equal')  # Equal aspect ratio ensures that pie is drawn as a circle.
plt.show()

Interpreting the Circle Graph

The circle graph shows that the President's salary accounts for 57.14% of the total salary, while the Vice President's salary accounts for 42.86%.

Conclusion

In this article, we created a circle graph for the highest federal salaries in the United States. We calculated the percentage of each category and used a pie chart to display the data. The circle graph shows that the President's salary accounts for 57.14% of the total salary, while the Vice President's salary accounts for 42.86%.

Future Work

In the future, we can use this circle graph to compare the salaries of different federal positions. We can also use this graph to visualize the salaries of different countries.
