This visualization allows you to visualize two variables against one-another in time. To use this visualization, you must make selections from the three drop-down menus. From the first two drop-down menus, choose the variables you want to plot. From the third, choose whether you want to visualize the gross revenue of each region in your chosen industry, or the share each region has in the global industry. Then, hit "Plot!" and a chart (along with more instructions) will appear.
