简约现代风格病例数据趋势分析不同年龄段人群分布信息

A central, prominent line chart showing "Total Cases Over Time" with a clear trend line. Surrounding it, place four smaller circular radar charts or bar charts, each labeled: "0-5 Children", "6-18 Youth", "Adults", "Elderly". Color-code each group distinctly. Use arrows or subtle connections to show the relationship between the main trend and subgroup patterns. Style: professional academic poster, minimalist design, white background, pastel color scheme for groups, dark line for main trend.
