Understanding relationships between sets is an important analysis task. The major challenge in this context is the combinatorial explosion of the number of set intersections if the number of sets exceeds a trivial threshold. To address this, UpSet, a novel visualization technique for the quantitative analysis of sets, their intersections, and aggregates of intersections was developed. This technique was developed by Alexander Lex, Nils Gehlenborg, Hendrik Strobelt, Romain Vuillemot, Hanspeter Pfister (InfoVis ’14).

UpSet2.0 is refactor of this tool with TypeScript. The refactor revamps the UI and adds new features like Provenance Tracking for redo and undo, custom data upload interface, support for embedding UpSet visualization in websites and using UpSet as a javascript library. Integrating provenance tracking was the focus of this refactoring and we developed a library for tracking provenance. The library tracks interactions in a graph. Each action results in a new node in the graph and the edge represents the action.
