Learning D3.js 4 Mapping - Second Edition: Build cutting-edge maps and visualizations with JavaScript

Key Features

• Dive into D3.js and apply its powerful data binding ability in order to create stunning visualizations
• Learn the key concepts of SVG, JavaScript, CSS and the DOM to bring data and shapes to live in the browser
• Solve common problems faced while building interactive maps
• Acquire key web development skills from the creating your interactive to testing and finally publishing it.

Book Description

D3.js is a visualization library used for the creation and control of dynamic and interactive graphical forms. It is a library used to manipulate HTML and SVG documents as well as the Canvas element based on data. Using D3.js, developers can create interactive maps for the web, that look and feel beautiful.

This book will show you how build and design maps with D3.js and gives you great insight into projections, colors, and the most appropriate types of map.

The book begins by helping you set up all the tools necessary to build visualizations and maps. Then it covers obtaining geographic data, modifying it to your specific needs, visualizing it with augmented data using D3.js. It will further show you how to draw and map with the Canvas API and how to publish your visualization. By the end of this book, you'll be creating maps like the election maps and the kind of infographics you'll find on sites like the New York Times.
