 <p>This book contains many code examples in an effort to teach the art and science behind creating interactive web-based graphics using <strong>plotly</strong>. To see the actual interactive result of the code (rather than a video or static version), you may want to run the code examples in a suitable computational environment. Visit <a href="http://bit.ly/plotly-book-cloud" class="uri">http://bit.ly/plotly-book-cloud</a> for a cloud-based instance of RStudio with all the required software to run the code examples in this book. Most, if not all of these code examples assume you have the <strong>plotly</strong> package loaded:</p>
