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.

In this recipe, we will integrate our first, real live map.

Getting ready

To get through this recipe, you must have a Google ID. If you do not have one, you will need to create one. Beyond that you will need to activate the Google Maps API v3 service in the API Console. For more information on this, please review the recipe Obtaining a Google API key discussed earlier in this chapter.

Our goal will be to create a full-screen Google map that will be zoomed in and focused on France:

How to do it...

Let's list the steps to create this sample. To create this sample we will create two files—a .html file and a .js file:

  1. Let's start with the HTML file. We'll create a basic HTML file baseline for our project:
