The aim of this design is to show the audience a quick overview of USA history in a certain period by visualizing the relationship between USA transportation, USA economy, and USA war.

In order to achieve the goal, 3 indicators were chosen to become the measurement standards. They are employee numbers in the USA transportation industry, USA unemployment rate, and US soldier number.

By comparing the collection date from 1900 - 1945, several key time periods can be seen. Analyzing the background events also helps to categorize the relationship for the 3 concepts and make the data more logical.
