Data Visualization Salary and Insights for 2025

The art of data visualisation is about telling a story with data. Here’s the only book you’ll need on the subject. 

 Data visualisation is an effective method to allow people (generally data enthusiasts) exhibit data; to permit them to interpret data. It’s the act of making a story out of data by converting spreadsheets of numbers into spectacular graphs and charts.

What is data visualization?

 Data visualisation can be defined as a tool or process where data and information are put into charts, graphs, maps, pictures or other visual representation to facilitate an easy understanding of any patterns, trends or outliers in them.

 Data visualisation also presents data to wider non-technical or expert audiences in an accessible way, such as the health agency of a government showing a map of vaccinated regions.

 A good data visualisation makes it easier for a decision-maker to see the wood for the trees; to make sense of a dull database; to see issues clearly, and therefore to decide what to do next.
