Alternatively, since the user's base year is 2025, maybe the chart includes 2021-2025 and then 2026-2033, but that's many periods. Given the user's example, maybe just use 5 periods. Let's create a segment-stacked chart with periods from 2021 to 2025 (historical) and then 2026-2030 (forecast), totaling 10 periods. But the user's example has 5 periods. To match the example's structure, perhaps use 5 periods. Let me check the user's example again: the example has periods ["2020", "2021", "2022", "2023", "2024","2025","2026","2027","2028","2029","2030","2031","2032","2033"], but the values only have 5 years. Wait, in the example JSON, the periods array is ["2020", "2021", ..., "2033"], but the values arrays are [10,12,15,18,20], etc., which is 5 data points. So maybe the user expects the periods to include the entire study period, but the values are only for the base years and a few forecasts. For the purpose of this task, I'll create a segment-stacked chart with periods from 2021 to 2025 (5 years) and then the forecast from 2026 to 2033 (8 years), but the example only includes 5 data points. To align with the user's example, maybe use 5 periods. Since the
