   We can use `labelLayout` to set font size based on the size of rect. For example:
   ```ts
   labelLayout: function (params) {
       if (params.rect.width < 5 || params.rect.height < 5) {
           return {
               fontSize: 0
           };
       }
       return {
           fontSize: Math.min(Math.sqrt(params.rect.width * params.rect.height) / 10, 20)
       };
   },
   ```
