Preface

Data is everywhere around us, and each day more of it is made available freely as open data or is published as a result of big data analytics. Although the data in itself is already really valuable, it is usually very difficult to present this data in a clear and concise way to a larger audience. D3.js gives us a way to easily represent this data and create standard-based, interactive data-driven visualizations, which can run on all devices, from phone to desktop. In this book, we'll explore all the different visualizations options provided by the D3.js APIs and show how you can use common patterns to create beautiful interactive visualizations using a minimal amount of coding. We'll also explore how you can prepare the data so that it can be easily visualized.
