Introduction

This d3.js parallel coordinates plot is another experiment in how we might use interactive plots in Javascript to represent a partykit / rpart object from R. The example builds on this d3.js collapsible tree plot. Eventually, it would be nice to combine the tree and parallel coordinates into a layout with synced interactivity.

### Almost No [`rCharts`](http://rcharts.io) Also, this is fairly different from most of my interactive plots from R in that it almost completely avoids [`rCharts`](http://rcharts.io) (almost because I did use its `publish` to make this gist). I chose to exclude `rCharts` for two reasons:
  1. demo how we can use htmltools to build html/js in R
  2. help users understand some of the things rCharts does f

[rPlotter]: Customised Palette Experiments

Introduction

I created a function called "extract_colours()" in my "rPlotter" package. Using this function, any image in PNG, JPG, JPEG or TIFF format can be converted into a simple colour palette.

YET, this is my very first attempt, the colours are only sorted by alphabetical order at the moment. More work is needed to arrange colours based on colour theory and other factors.

Example 1a - R Logo R Logo

Output 1a
