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.
Under About is a brief introduction to this app.
Below is a screenshot of the app:
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.
