_In the example here, data about the discovery of moons of Jupiter is presented in four "stages" of a story, each of which itself offers brushing and linking between the two plots shown. The origin of this plot is explained in this video narrated by Josh Peek. Technical steps to creating this figure: 1) ingest data to [Glue](http://glueviz.org), a desktop linked-view visualization tool written in Python by Chris Beamont; Beaumont;  2) output Glue results to [d3po](http://d3po.org) (a prototype linked-view web tool written in d3 (javascript) by Adrian Price-Whelan and Josh Peek); 3) ingest the d3po javascript output to [Authorea](http://authorea.com), producing the interactive figure shown above. For reference, Glue and similar programs can also output to other javascript plotting tools, such as [Plot.ly] (http://plot.ly), which are rapidly becoming more flexible and robust than prototypes like d3po._
