Configure the layout when instantiating a Graph:

const graph = new G6.Graph({
  ...                      // Other configurations
  layout: {                // Object, configuration for layout. random by default
    type: 'force',
    preventOverlap: true,
    nodeSize: 30,
    ...                    // Other layout configurations
  }
});

The configurations of each layout algorithms are different. Please refer to corresponding API of each layout in this directory.
When layout is not assigned on graph:

• If there are x and y in node data, the graph will render with these information;
• If there is no positions information in node data, the graph will arrange nodes with Random Layout by default.

The following functions are used for register a new type of layout. If you are using built-in layouts, you do not need to controll the functions below, which are called by graph automatically.
