Lightweight Provenance-Driven Exploration

I’m interested in how interactive tools can encourage users to go beyond a single default visualisation for a data set or simulation, ex-ploring and comparing alternatives in the hope of gaining a deeper understanding. Here I present two prototype interfaces that tackle this by reifying provenance: one gives the user explicit, instant ac-cess for revisiting parameter values that have been tried over the course of an exploration; the other ties provenance values to the visualisation marks themselves, to guide the user towards settings that lead to interesting alternative results. My hope is that the prin-ciples of these interfaces can be deployed more broadly, on general sensemaking tasks
