### Interactivity : Linking Views and Staging  A simple interactive figure gives its user an experience of playing with data, but in a very limited sandbox. Many top-tier news agencies (e. g. *The York Times*) have used and helped develop technology (e.g. the javascript library known as [d3](http://d3js.org)) that allows for the creation of interactive figures without a need for foyor  dedicated developers. Three key features of the emerging paradigm for ineractive communication of quantitative information are _Brushing_, _Linking_, and _Staging_. * _Brushing_ is the idea of being able to select, with a box or lasso like tool, a subset of the points in a one- or two- dimensional space.
