Using Tableau, create a visualization that shows for each segment, the Profit to Sales ratio across different regions. That is, looking at your visualization, it should be possible to compare the performance of a segment in different regions. You should be using an aggregate calculated function and not be summing the profit to sales ratio for a given region per order. For a given segment and region, you should first get all the sales, then get all the profit, and then take the ratio of the two.

You should consider making appropriate design choices that results in an effective visualization (legibility, color, labels, etc.)
