Data Stories 80 | Indexical Visualization with Dietmar Offenhuber
We have Dietmar Offenhuber, Assistant Professor at Northeastern University, on the show again to talk about “Indexical Visualizations”: visualizations that reduce the gap between the recorded phenomenon and its representation.
In Dietmar’s words: “If we understand ‘data’ as a collection of symbolically encoded observations, could we think of a display that conveys information—without the symbolic encoding of data—through the object itself?”
On the show we talk about strategies to define and build indexical visualizations. Dietmar provides numerous examples, including thermometers, tree rings, petri dishes, and the blinking lights in your router. He also offers tips on experimenting with this kind of visualization and connecting to the indexical vis community.
If you enjoy this episode you may also want to listen to our previous episode with Dietmar and to our “data sculptures” episode with Domestic Data Streamers.
Enjoy the show!
