The tool is interactive. There are 4 checkboxes on the graph, representing Data Analytics, Data Scientist, Business Analytics, and Data Engineer. If you check the checkbox which represents a job title, the d3 graph will show some circles. Every circle represents a state in the United States. The position in the map of the circle represents the state location. The radius of the circles represent the salary level. The larger the radius is, the higher the average salary is. By checking the checkbox, you can see the salary of every state intuitively.
