Data Visualization is one of the most prevalent and ubiquitous approaches used for analytics.

Complex statistics, even when they are as simple as bar graphs, tend to turn individuals and groups into uncontrollable entities. Without proper understanding, they become statistics that can’t be easily manipulated. For example, by observing how a series of values changes over time, a data scientist can learn where trends or changes in the data are taking place. Sometimes this ability is easy to discover, but sometimes you need to work with data that’s much more complex than a simple bar.
