Data visualization with Java JFreeChart

JFreeChart is a popular open source chart library built in Java. It's used in various other open source projects as well such as JasperReports (open source reporting framework). You can build a number of popular charts such as pie charts, time series charts, and bar charts to visualize your data with this library.

JFreeChart builds the axis and legends in the charts and provides automatic features such as zooming into the charts with your mouse. For simple chart visualizations that the developer can use to build the models (using lesser data) JFreeChart is good but for extensive data visualization that you need to ship to your customers or end users you are better off with an elaborate data visualization product such as Tableau or QlikView over big data. Although we will cover some of the charts from JFreeChart, this chapter is by no means an extensive take on JFreeChart.

For this book and its examples, we use these charts extensively for visualizing...

Apache Spark Quick Start Guide

Apache Spark Quick Start Guide

Apache Spark is a ?exible in-memory framework that allows processing of both batch and real-time data. Its unified engine has made it quite popular for big data use cases. This book will help you to quickly get started with Apache Spark 2.0 and write efficient big data applications for a variety of use cases.

Mastering Machine Learning with Spark 2.x

Mastering Machine Learning with Spark 2.x

The purpose of machine learning is to build systems that learn from data. With the meteoric rise of machine learning, developers are now keen on finding out how can they make their Spark applications smarter. The book commences by defining machine learning primitives by the MLlib and H2O libraries. You will learn how to use Binary classification to detect the Higgs Boson particle in the huge amount of data produced by CERN particle collider and classify daily health activities using ensemble Methods for Multi-Class Classification. Finally, you will build different pattern mining models using MLlib, perform complex manipulation of DataFrames using Spark and Spark SQL, and deploy your app in a Spark streaming environment.
