Google Visualization API Essentials

Overview of this book

There's a lot of data in our world, and visual representations are often the best method of making sense of it all. Yet, it should not take an army of programmers and analysts to create visualizations in order to make data useful. The Google Visualization API is accessible to novice and advanced programmers alike, making data useful to more people."Google Visualization API Essentials" will show you how to create interactive data displays with very little code. The API, combined with Google Spreadsheets and Fusion Tables, is a complete system, from data management to analytical displays. Not only is it simple to learn, but the Google Visualization API can also be viewed as a first step to learning additional Google APIs."Google Visualization API Essentials" uses both methodology overviews and hands-on examples with real data to introduce chart and graph creation on the Google platform. Topics are presented from various aspects, including Google Spreadsheets and Fusion Tables, and Graphic User Interfaces. An overview of the various API development environments available to developers is also covered. Basic and advanced charts, data source connectivity, style formatting, and publishing options are also explored in depth."Google Visualization API Essentials" brings the arsenal of Google Visualizations into the web developer toolkit.

Common structure


At its core, the Visualization API acts as a bridge between a data source that contains data and an HTML page displaying the data. Regardless of platform, the Visualization API follows the same architecture as other Google API products. Methods to use for Google APIs consequently also follow the same general structure as APIs from other application providers such as Flickr or Facebook. For most APIs, including the Google APIs, the JavaScript namespace structure is as follows:

application.category.function(variables)

For example, to create a new pie chart with the Google Visualization API, the corresponding code would be as follows:

new google.visualization.PieChart(document.getElementById('visualization'));

For non-code based platforms, such as Spreadsheets and Fusion Tables, the user interface that encapsulates the Visualization API is designed to enhance the strengths of a particular tool set for a wide spectrum of users. For example, Fusion Tables is primarily focused on...
