B. A waterfall chart is specifically designed to illustrate how positive and negative values contribute to a total over a series of sequential steps or categories. It shows the cumulative effect of each value, making it ideal for visualizing changes in a process, financial statement, or any scenario where values are sequentially introduced and impact a total. Therefore, a waterfall chart would best serve the data analyst's needs in this scenario.
