Chapter 3. Data Visualization
Sometimes, we don't know how valuable data is until we look at it. In this chapter, we get into a Web Visualization Framework called D3 (Data-Driven Documents) to create visualizations that make complex information easier to understand.
In this chapter we will cover:
Data-Driven Documents (D3)
Getting started with D3.js
Bar chart
Pie chart
Scatter plot
Line chart
Multi-line chart
Interaction and animation
Exploratory data analysis (EDA) as mentioned in Chapter 1, Getting Started, is a critical part of the data analysis process because it helps us to detect mistakes, determine relationships and tendencies, or check assumptions.

The four types of EDA are univariate non-graphical, multivariate non-graphical, univariate graphical, and multivariate graphical. The non-graphical methods refer to the calculation of summary statistics or the outlier detection. In this...
