This data visualisation is exploratory. It is a tool for rendering the city as a playground to explore by foregrounding smell over over sensory modalities by following a sequence of smell narratives across the city. Walk the trail for real if you are there. And if you cannot be in Paris let the smell notes (of a range of associative smell memories) and the locations generate olfactory images of classic Parisian scents, smells and aromas in micro-narrative form.
Still at prototype stage this Virtual Smellwalk of Paris currently features just three smell walks around the city out of a possible total of 8.7 x 10^9.
