$1\mathrm{.}2$ What is data visualization?

Introduction to data visualization

Data visualization is the display of data in a format, such as a table or chart, that seeks to achieve a goal of conveying particular information to a viewer. Data presented in a text$-$only format often does not convey information well. Ex Given this text$-$only data on $2013$ median house prices in southern California counties, finding the price for a particular county is inconvenient: Los Angeles $$405,000.$ Orange $$661,000$; Riverside $$306,000$; San Bernardino $$192,000$; San Diego $$473,000$; Ventura $$464,000.$

Instead, displaying the data visually as a table better conveys the information. A table displays data using rows and columns.
