Creating scatter plots with Bokeh-Scala

While Zeppelin is powerful enough to quickly execute our Spark SQLs and visualize data, it is still an evolving platform. In this section, we'll take a brief look at the most popular visualizing framework in Python, called Bokeh, and use its (also fast evolving) Scala bindings to the framework.

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
