_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 details: the software stack steps  to create creating  this example is: figure:  1) ingest data to [Glue](http://glueviz.org), a desktop linked-view visualization tool written in Python by Chris Beamont; 2) output Glue results to d3po [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, [Authorea](http://authorea.com),  producing the interactive figure shown above._ 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._
