Parasol

https://parasoljs.github.io/

Parasol is a JavaScript library for visualization of multi-objective optimization problems. It features interacitve 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.

This library is based on D3 V5 API and extends upon parcoords-es.
