Q: What does the task scatter plot do?

We are putting together a dashboard and are wondering if the scatter plot should be included. What insights can we get from it above what is shown in the histogram/cumulative probability.

A: The scatter plot is an valuable visualization to show the relationhips between one variable and another. In task scatter plot, for each iteration it plots the task cost or duration vs the project cost or duration. From the pattern of the dots, we can see how tightly correlated the project results are to the task results.
For example in the scatter plot below there is a relatively strong positive relationship between the project cost (y axis) and the task cost (x axis) . This is indicated by the football shape of the plot as well as its orientation of bottom left to top right. This indicates that this task is a main driver of the project cost.
