Visualizing data

Graphs and charts are used to gain a better understanding of the data relationship. We will use the following to explore data visually:

Combination of Spark and Vegas viz
Spark Notebook

Vegas viz for data visualization

Vegas viz is a MatPlotLib-like library for Scala and Spark. The documentation for this library can be found at https://github.com/vegas-viz/Vegas. Spark does not contain any built-in support for data visualization. Vegas viz provides a convenient mechanism to add visualization to a Spark program written in Scala.

In order to use this library with Spark, let's add the following dependencies to build.sbt:
