ui.diagram

Since 8.3

A powerful widget for building graphs.

Diagram is an advanced tool designed for building diagrams of any complexity. It is extended with the predefined set of types, but also allows creating custom SVG-based shapes. Links and blocks can be arranged automatically or be at the fixed coordinates.

Constructor

webix.ui({
  view:"diagram",
  data: [
    { id: "1", value: "Block 1", type: "plus"}
  ],
});
