Bar Charts are predominantly used to demonstrate the changes in an amount of something changing discretely, e.g. to analyze the difference between the revenue got from sales by manager or to visualize some questionnaire results. 3D is a visual setting that can only make your chart look more attractive, but it has no additional information to give to your customers.
This Chart has only one 3D Bar series. A 3D effect is done through the bar3d() method. This series demonstrate the sales of the top 10 cosmetic products. The X-Axis is rotated vertically and it holds the categories - the names of the products. The Y-Axis, oppositely, is rotated horizontal and demonstrates the values in a range from $0 to $280 000. Each tooltip displays the information about its own point, adjusted to be stuck to the right side of the bar by its left side.
