What will you build today?
Node based applications
Create components to render rich content and interactivity in your nodes and groups. Wire them up with a view and apply an automatic layout. VisuallyJs makes it a snap to build callflow designers, chatbot builders, kanban boards, automation flows, and so much more.
Diagrams
Render SVG shapes using shape libraries. Shrink, grow and rotate using our resizing tools. Drag new shapes onto your canvas from a palette. Everything you need to build world-class diagrams is available out of the box. Build flowcharts, BPMN editors, call flow builders, SCADA/HMI consoles, process flow diagrams, ERD editors, mindmaps and much more.
Charts

Full range of 2D charts - column, bar, area, line, scatter - plus pie charts, gauges and more specialized charts such as sankey.

Populate charts from standalone data or use the data model from an app or diagram for dynamically updated insights into your dataset.

Dashboards
Create a model and use it as the single source of truth for a mix of apps/diagrams and charts. The possibilities are endless.
