Data visualization is an important skill that will be used often when communicating results with stakeholders. Describe to me one of your most innovative data visualization ideas that went beyond pie and bar charts.

Data Science and analysis of complex data sets is a very technical discipline. However, the organization's stakeholders who use the results of the analysis need to be able to clearly understand what the data is telling them and use it to improve their operations and help them make business decisions. You need to be able to present your work in a manner that is easy to understand and utilize. This is known as data visualization. The interviewer is seeking to understand how you organize and present the data to accomplish this objective.

"While the process of analyzing data is important, the results of the analysis must be useful to the stakeholders in the organization. It is important to understand what the stakeholders' objectives are when deciding how to present my results. One method I've found to be effective is to add graphs, pictures, and illustrations to my presentations and reports. Once, when presenting an analysis of customer usage trends for a product our organization sold, I incorporated images of the product and animated them to expand in size in relation to the growth in customer adoption, adding the statistics and actual growth numbers. The audience remarked how clear this made the information."
