This website explains and partially documents the R package plotly, a high-level interface to the open source JavaScript graphing library plotly.js (which powers plot.ly). The R package already has numerous examples and documentation on https://plot.ly/r and https://plot.ly/ggplot2, but this website provides more of a cohesive narrative to help explain fundamental concepts and recent developments. By reading from start to finish, readers new to R and plotly should be able to get up and running fairly quickly. That being said, advanced R and plotly users should still find the majority of this material useful and informative. I highly recommend copying/pasting examples into your R console, and modifying them as you read along, to aid the learning process.
