This is the age of data. There are more innovations and more opportunities for interesting work with data than ever before, but there is also an overwhelming amount of quantitative information being published every day. Data visualisation has become big business, because communication is the difference between success and failure, no matter how clever the analysis may have been. The ability to visualize data is now a skill in demand across business, government, NGOs and academia.
Data Visualization: Charts, Maps, and Interactive Graphics gives an overview of a wide range of techniques and challenges, while staying accessible to anyone interested in working with and understanding data.
- Focusses on concepts and ways of thinking about data rather than algebra or computer code.
- Features 17 short chapters that can be read in one sitting.
- Includes chapters on big data, statistical and machine learning models, visual perception, high-dimensional data, and maps and geographic data.
- Contains more than 125 visualizations, most created by the author.
- Supported by a website with all code for creating the visualizations, further reading, datasets and practical advice on crafting the images.
Whether you are a student considering a career in data science, an analyst who wants to learn more about visualization, or the manager of a team working with data, this book will introduce you to a broad range of data visualization methods.
Cover image: Landscape of Change uses data about sea level rise, glacier volume decline, increasing global temperatures, and the increasing use of fossil fuels. These data lines compose a landscape shaped by the changing climate, a world in which we are now living. Copyright © Jill Pelto (jillpelto.com).

Robert Grant is a British statistician specialising in data visualization and Bayesian models. He worked in biomedical research and taught statistics at St George's Medical School, Kingston University, the Royal College of Physicians of London, and the National Institute for Health and Care Excellence before launching his own training and coaching business, BayesCamp, in 2017.

"… Data visualization is a very useful tool for this, but only when used well. That is what this book offers: visualization techniques, a link with statistics, principles for designing a good visualization, and lots of examples. The author aims to teach a way to design graphics that have an impact. The author is a statistician and this is reflected in the way he approaches the topics: for example, there is no display of error bars without explaining what they represent …. Examples are the backbone of the book, each chapter has one or more visualizations to compare what the advantages are to present data a certain way … without forgetting the reasoning behind it, whether it be statistical or visual). This makes the book very readable and appealing."

"This book gives a large number of interesting tips and suggestions for anybody (statistician or not) who wants to use graphics to represent and convey the information contained in their data. Before going into a more detailed analysis of the strengths and weaknesses of this book, it is worth remarking on its very broad descriptions, analysis and overview of graphics, not so much from a statistical and mathematical point of view as a cultural point of view, considering also the physiology of the brain... Comparisons of important concepts are very well presented through clear and effective examples and graphs: for instance, differences between correlation and causation, joint and marginal distributions, interpretation and use of counts and percentages, means and medians (even if some graphs compared in the examples do not have the same axis scales, neither in the paper version nor in the online one), meaning and interpretation of the effect of confounders and interactions in a statistical model. An intuitive approach is used to explain several complex concepts like artificial intelligence and convolutional neural networks. Some common mistakes (sometimes due to misunderstanding) are presented and commented on in a very clear way...this book is highly recommended to researchers of all fields who want to learn about how to start a data analysis in a proper way, how to present their data and results clearly and attractively, and how to avoid mistakes that can jeopardize their work."
