d3 parallel coordinates categorical axis select

building on timelyportfolio's block: d3 parallel coordinates with outside filters


Idea

Working on a project that would like outside categorical filtering to work with d3 parallel-coordinates, so I poked, prodded, and hacked to end up with this proof of concept.

Categorical Click Selection

Once we proved the mechanism is possible, we can add a categorical axis from our prototype to provide a potentially more intuitive mechanism to filter categorical data like cyl/cylinder data from the mtcars dataset in R.

I used an experimental branch of the R htmlwidget parcoords to save me some coding.
