This document discusses visual conversations with data through explanatory and exploratory data visualizations. It provides examples of visualization tools like ggplot2 and d3.js and techniques like exploiting hierarchical structure with treemaps, using pivot tables, and creating macroscopes. The document advocates having visual conversations with one's own data to discover patterns and differences in an emergent and interactive way.
16. Explanatory visualization
Data visualizations that are used to
transmit information or a point of
view from the designer to the
reader. Explanatory visualizations
typically have a specific “story” or
information that they are intended
to transmit.
Exploratory visualization
Data visualizations that are used by
the designer for self-informative
purposes to discover patterns,
trends, or sub-problems in a
dataset. Exploratory visualizations
typically don’t have an already-
known story.
Visual Conversations with Data Datasets often contain amyriad number of stories,but how can we best make sense of them? Maybe avisual conversation can help? 30 mins

Brief explanation of chart and what the labels are.
Wheel diameter, actual distance travelled
Livescribes, process of creation of the rich picture… the diagramming is an active storytelling process that builds on itself amd has potentially many narrative threads
Also how you position marks on a canvas in relation to each other

The top, blue strip shows the gear (1 to 7); the green strip shows the throttle pedal depression (0-100%), and the red strip shows the brake (0-100%). The light blue strip is a composite of the previous three strips. The whiter the pixel, the closer it is to 100% throttle in 7th gear with no braking.The bottom two traces show the longitudinal and lateral g-force respectively. For the longitudinal trace, red shows braking – being forced into the steering wheel; green shows acceleration – being forced back into your seat. You’ll see the greatest g-force under braking occurs when the brakes are slapped full on… (the red bits in the third and fifth traces line up). For the latitudinal g-force, the red shows the driving being flung to the left (i.e. right hand corner), the green shows them being pushed out to the right.
