Using the web browser as a development tool

Although any modern browser supports Scalable Vector Graphics (SVG) and has some kind of console, we strongly recommend you use Google Chrome for these examples. It comes bundled with developer tools that will allow you to very easily open, explore, and modify the code. If you are not using Google Chrome, please go to http://www.google.com/chrome and install Google Chrome.
