This book compares bitmap and vector drawing approach by showing both canvas-based drawing and Raphaël drawing code examples.
Most of the code examples in latter part of book uses d3.js for social network data visualisation.
This book has detail code example of using OAuth with Facebook and Twitter.
It may serve as a quick guide on how to access different social network API, including Facebook, twitter, Google+ and StackOverflow.
Very good for beginner to kick start both visualisation and social network API connection.
Doesn’t provide much in depth code example on each topic. For example, this book doesn’t discuss how to make use of Facebook graph API to get complex objects relationship.
Not a book for whom to have detail usage example on particular drawing libraries.
