Structure Complex Diagrams with Layered Views

December 3, 2025
JointJS+ 4.2 introduces a flexible Layers API that improves diagram organization, visibility control, and interactivity management.

JointJS+ is a diagramming library that offers advanced features like custom shapes, data binding, and advanced layout algorithms, enabling you to create complex, interactive, and visually appealing diagrams. It includes a ready-to-use demo application that showcases its functionality and serves as a starting point for your own diagramming projects.

The JointJS+ 4.2 update introduces a redesigned Layers API that gives developers more control over diagram structure, interaction, and presentation by allowing cells to be grouped into independent layers with their own attributes, stacking context, and event flow. This enables clearer organization of complex graphs, more predictable z-index behavior, and the ability to apply targeted styling, filters, and animations at the layer level, all while maintaining backward-compatible event handling for smoother integration into existing applications.
