Wait, the example JSON provided by the user has periods as ["2020", "2021", "2022", "2023", "2024","2025","2026","2027","2028","2029","2030","2031","2032","2033"], which is from 2020 to 2033. But in our case, the study period is 2021-2033. So the periods would be 2021 to 2033. However, the base year is 2025, which is part of the historical range. So the historical data is 2021-2025, and the forecast is 2026-2033. For the chart, maybe we can show the historical data from 2021-2025 and the forecast up to 2033. So the periods would be 2021, 2022, 2023, 2024, 2025, 2026, 2027, 2028, 2029, 2030, 2031, 2032, 2033. That's 13 periods. But the example uses 5 periods. However, the user's instruction says to use real market segments and periods must be years. So I have to proceed with the correct periods.
