  import { Button } from "wx-svelte-wx";
  
  const data = getData();
  
  let api;
  
  const updateLink = () => {
        api.exec("update-link", {
            id: 1,
            link: { type: 3 } 
        });
    };

</script>

<Button click={updateLink} type="primary">Update Link</Button>

<Gantt
  bind:api
  tasks={data.tasks}
  links={data.links}
  //other settings />
