Title in Ant Design Charts is used to specify the title of the chart.

Titles can be configured at the level of mark:

({
  title: {
    title: 'hello',
    subtitle: 'world',
  },
});

Titles can also be configured at the level of view:

({
  title: {
    title: 'hello',
    subtitle: 'world',
  },
});

chart.title({ title: 'hello', subtitle: 'world' });

More options about title, see the API document of title.
