NZZ Wandelhalle
An interactive network for NZZ tracing who walks the Swiss parliament's lobby — and on whose behalf.
Who actually walks the lobby of the Swiss parliament? For the Swiss newspaper NZZ, I built “Wandelhalle”, an interactive visualization that explores the true interests of lobbyists (full article) — commissioned through OpenDataCity with data journalist Lorenz Matzat, for NZZ’s Sylke Gruhnwald.
The visualization is built with d3.js. It began as a radial layout in the tradition of Mike Bostock’s examples, but over many iterations the visual language was redefined into something of its own — a playful, explorable network in which users can trace who is connected to whom, and on whose behalf.
The project went through an unusually visible design process: I documented the iterations in a Flickr stream, kept the prototypes online — including an experimental graph-view transformation that hints where the form could go next — and published the code.
