We\'ll use this to power our D3.js visualizations in real-time (without updating the browser) and to make them interactive, fun & dynamic.We\'ll also be creating 3 projects to put our D3 & Firebase skills to the test - first of all a money planner called Ninja Wonga, then a fitness tracker called The Dojo and finally a company employee tree diagram called Ninja Corp. ...Why all the ninjas?I\'m also known as the Net Ninja on YouTube, with over 200,000 subscribers and nearly 1000 free development tutorials.
