1. Use Tableau Superstore data set Your manager at the Global Super Store is looking for an analysis of the returns by sub- category. They're concerned that returns are increasing more than sales. The first thing you'll need to do to answer their concern is to see sales and returns over the last few years. Create a line graph to show the trend by month and year for returns and total sales. Then you'll want to see what the relationship is between sales and returns in each subcategory. Create a bar chart to show the percentage of total sales in each sub-category that are returned and those that aren't returned. Should your manager be concerned that returns are increasing more than sales? Why or why not
