### Staging  Staging is a storytelling tool, allowing the author to reveal or highlight parts of a figure in sequence. The highlighting can take the form of Brushing and Linking as above.  ## Images in Context  Most observational astronomy has the unique feature of having a specific map to which the data are attached: the celestial sphere. As such, it makes sense for us to attach our images to locations. The AstroExplorer tool (cite) and the [ADS All Sky Survey](http://adsass.org) can allow images to be treated as data, in the sense that they can be "put back" on the Sky in context. Here's a sample, using an image from Barnard that is 100 years old (update). Click the caption's link to see it on the Sky in WorldWide Telescope.
