Final answer:
The delta mode in Visual Business Director could show the volume difference between a new product and existing products. This mode is designed to assess changes and compare different scenarios in business analytics.
Step-by-step explanation:
After launching a new product, the delta mode in Visual Business Director (VBD), which is a tool often used in business analytics and decision management, could show the volume difference between the new product and existing products. The delta mode is a feature of the Visual Business Director that allows users to compare different scenarios or assess changes over time. While options B and D may provide important data points, they are not features of the delta mode in VBD specifically. Option C is incorrect as delta mode does not represent data via color-coded shapes, but rather through quantitative differences in volume.
