Abstract (Summary)
Libra+ describes interactive visualization through the event that initiates an action, the object affected, and the response presented to the user. Reusable instruments implement these behaviors and can be assembled across layers or views. Coordination mechanisms address competing inputs, linked updates, and customized responses. Built on Libra.js, the library demonstrates how developers can combine simpler behaviors into richer interfaces and adapt interactions to different chart types.
