This web app has two tabs on the top: Home and About.

Under Home is the main app, including the interactive data input panel on the left side, and the data display on the right side.

On the left side of the app, you will be able to adjust your selections by: Rank, Growth (by Percentage), and by State/Province. To avoid empty display, the default state/province has been set to “GA.” To change the selection of state/province, you will need to delete the default and type in an abbreviation of a state or province.

On the right side, you will see the corresponding results based on your selection of ranges of ranks, growth, and state/province. You can also use the arrows next to each column name to sort the results. You can also search the results using the “Search” box.

Under About is a brief introduction to this app.

Below is a screenshot of the app:
