HTML5 Graphing and Data Visualization Cookbook

By: Ben Fhala

Overview of this book

The HTML5 canvas tag makes creating any plot shape easy, all you have to do then is fill it with exciting visualizations written in JavaScript or using other visualization tools. "HTML5 Graphing and Data Visualization Cookbook" is the perfect break into the world of Canvas, charts, and graphs in HTML5 and JavaScript. In this book we will go through a journey of getting to know the technology by creating and planning data-driven visualizations. This cookbook is organized in a linear, progressive way so it can be read from start to finish, as well as be used as a resource for specific tasks.This book travels through the steps involved in creating a fully interactive and animated visualization in HTML5 and JavaScript. You will start from very simple "hello world"ù samples and quickly dive deeper into the world of graphs and charts in HTML5. Followed by learning how canvas works and carrying out a group of tasks geared at taking what we learned and implementing it in a variety of chart types. With each chapter the content becomes more complex and our creations become more engaging and interactive.Our goal is that by the end of this book you will have a strong foundation; knowing when to create a chart on your own from scratch and when it would be a good idea to depend on other APIs.We finish our book in our last two chapters exploring Google maps and integrating everything we learnt into a full project.

Customizing controls and overlapping maps

The goal of this recipe is to practice working with Google Maps. We will integrate what we learned about working with Google Maps in this chapter and incorporate our control over the user behaviors, such as what controllers the user can use, into it. We will start digging into creating our own unsupported undocumented behaviors, such as locking the users' pan area.

Our main task in this recipe will be to take our work from the previous recipe, and instead of having the map zoom in and move around, create clean transitions between the zoomed in and zoomed out options; but as that isn't supported in a clean way through the interface, we will use external focuses. The idea is simple; we will stack up two maps on top of each other and fade in and out the top map, giving us total control over the fluidity of the transitions.

Getting ready

Even though we are starting from scratch, a lot of the work that we did in the last recipe is being re-used, so I strongly...
