If you are interested in creating maps for the web GIS data, this book is for you. Familiarity with D3.js will be helpful but is not necessary.

In Detail

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 based on data. A consolidated resource on obtaining geographic data, modifying it to your convenience, and visualizing it with augmented data using D3.js, this book will meet your mapping needs.

Starting with a working map, you will explore the tools required to start the construction process, further moving on to cover the fundamentals of SVG and understanding its relation to creating maps using D3. Equipped with this overview, you will learn to make optimum use of D3’s mapping, covering the main enter, update, and exit methods that allow D3.js to do its magic. Dealing with data joining and pairing with HTML and SVG, you will be introduced to different aspects of GEO data, along with the common file formats and converting data into GeoJSON and TopoJSON. You will learn to apply interactivity to your maps and create stunning visualizations before  finally ensuring problem-free development with a chapter on troubleshooting.
