Parasol: JavaScript library for multi-objective visualization

Parasol is a JavaScript library for visualization of multi-objective optimization problems. It features interactive linked plots, a data grid, and an array of clutter reduction techniques allowing for efficient visualization of trade-off in high-dimensional data. Parasol aides decision making by converting the paradox of choice into tangible solutions.

The library was published in a 2019 Environmental Modelling and Software paper. In 2026, we released version 2.0 which has modern dependencies, ready to use via npm. The GitHub repository is also available.
