The interactivity of the visualization allows for this massive data set to be represented with a simple bar graph, as well as allowing the end user a variety of options for the amount of detail they wish to view. Not only does this allow for high data density, but it actually gives the user control over the data density (Tufte).

Making the visualization interactive has a second purpose. Since the bar and blocks already embody the idea of fulfilling ones nutritional requirements, the interactivity additionally forces the end user to become an active participant in their own nutrition, thereby encouraging them to actually act on the visualization (Galloway).

The feedback from class was very helpful, and led to the ability to collapse sets of data since the complete data set isn't entirely necessary at all times. Displaying potential ingredients by rendering them translucently was also a suggestion from class, which is much easier to see than displaying it in the same way Tetris displays upcoming blocks.
