The document discusses using data to generate music, visualizations, and food. It introduces the concept of "data gastronomification" where data is represented through food items and recipes. A new R package called geom_taco is presented, which allows data to be plotted as tacos with different fillings representing variables.

We need more dimensions!
Three dimensions
in this plot:
Sepal Length,
Sepal Width,
Species
Adding dots is easy.
Adding dimensions is hard.

Reasons we liked R
for data music videos
● Audio generation for music
● Vector graphics for video
● Data connectors to everything

Data guacamole
● New York City math test scores
– 32 districts
– 6 grades (3rd through 8th)
– 7 years (2006 to 2012)
● A bowl for each year
● Levels of ingredients based on

Why we wrote geom_taco
● Dependence on human experts limits
gastronomification
– Data guacamole
– OpenSauce
– Census Spices
● geom_taco uses commodity
infrastructure
– Robust, scalable, inexpensive

geom_taco (open source)
● A geom for ggplot
● Non­visual aesthetics
– Fill
– Salsa
– Guacamole
