For 2021, maybe the market size was USD 2.0B. Then each segment's share. But this requires a bit of calculation. Alternatively, use the base year 2025 data and project forward. Since 2025 is the base year, the current size is USD 3.1B. Let's use 2021 as the starting point. If the CAGR is 6.5% from 2021 to 2033, then 2021's market size would be 3.1B / (1.065)^4 ≈ 2.5B. Then each segment's share can be calculated. But this is getting complex. Maybe the exact numbers aren't crucial for the example, as long as the segments are realistic and the growth direction is correct. The user's example uses [10, 12, 15, 18, 20] for Product A, etc. So I can create similar data but with more years. However, the user's JSON example only includes 5 years. Wait, the user's example has periods as ["2020", "2021", "2022", "2023", "2024","2025","2026","2027","2028","2029","2030","2031","2032","2033"], which is 14 years. The values arrays have 5 entries. That's a problem. The example JSON seems to have a mismatch. The example given by the user has periods as 14 years but values as 5 entries. That's an error. The user's instruction says to use real market segments and periods. So perhaps the chart should cover the study period from 2021 to 2033, with the periods array as ["2021", "2022", ..., "2033"], but the values for each segment should have data for each year. However, without actual data, this is challenging. Since the user wants a placeholder for the chart, maybe use the example structure but adjust the periods to fit the study period. The example uses 5 years, but the user's study period is longer. This might be a mistake in the example, but I need to follow the structure. Alternatively, perhaps the user expects a simplified version. Let's proceed with the example's structure but adjust the periods to 2021-2033 and create a realistic but placeholder-like data. The key is to have the segments and periods correctly labeled. For instance, if the base year is 2025, the periods could be 2021 to 2025 for historical and 2026-2033 for forecast. But the example uses a segment-stacked chart, which requires values for each segment across all periods. Since I can't calculate exact numbers without more data, I'll create some sample data. For example:
