import MindMap from "react-mindmap";
import { nodes, connections } from "./my-map.json";

class Example extends Component {
  render() {
    return (
      <MindMap nodes={this.props.nodes} connections={this.props.connections} />
    );
  }
}

render(
  <Example nodes={nodes} connections={connections} />,
  document.getElementById("target")
);

connections	Array	[]	Array of objects used to render connections.
subnodes	Array	[]	Array of objects used to render subnodes.
editable	Boolean	false	Enable editor mode, which allows to move around nodes.

nodes

Array of objects used to render nodes. Below an example of the node structure.

{
  "text": "python",
  "url": "http://www.wikiwand.com/en/Python_(programming_language)",
  "fx": -13.916222252976013,
  "fy": -659.1641376795345,
  "category": "wiki",
  "note": ""
}

The possible attributes are:

• text: title of the node
• url: url contained in the node
• fx and fy: coordinates (if not present they'll be generated)
• category: category used to generate an emoji
• note: note that will be visible on hover

connections

Array of objects used to render connections. Below an example of the connection structure.

{
  "source": "python",
  "target": "basics",
  "curve": {
    "x": -43.5535,
    "y": 299.545
  }
}

The possible attributes are:

• source: title of the node where the connection starts
• target: title of the node where the connection ends
• curve.x and curve.y: coordinates of the control point of a quadratic bezier curve (if not specified the connection will be straight)

subnodes

Array of objects used to render subnodes. The structure is the same as for nodes with two additional attributes:

• parent: title of the parent node
• color: used for the margin color, needs to be a valid CSS color

• .mindmap-subnode-group-text: foreignObject element containing all subnodes of a given node;
• .mindmap-subnode-text: div element containing a subnode;
• .mindmap-connection: path element for each connection;
