    start: "2025-01-13",
    end: "2025-02-21",
    progress: 21.818181818181813,
  },
  {
    id: "002",
    name: "002",
    start: "2025-01-06",
    end: "2025-02-19",
    progress: 100,
  },
  {
    id: "003",
    name: "This should be longer task",
    start: "2024-11-29",
    end: "2025-02-18",
    progress: 100,
  },
  {
    id: "004",
    name: "004",
