- added the ability to embed the scatterplot inside the returned json data with data: uris (although it doesn't seem to work well)
- connected the selection logic to the scatterfacets (although it doesn't seem to filter the rows... and I'm puzzled as why)
- reduced cut/paste and code overlap between the scatterplot generator and the scatterplot facet
