You have a dataset that has four fields named Category.

Sales:  B. Columns

Profit:  D. Rows

Customer Name:  C. Detail on the Marks card

Category:  A. Color on the Marks card

To create the visualization, you need to drag Sales to Columns, Profit to Rows, Customer Name to Detail on the Marks card, and Category to Color on the Marks card. This will create a scatter plot that shows the relationship between Sales and Profit for each Customer Name, with different colors for each Category.
