G2 · 花瓣玫瑰图

单变量分类计数，≤8 类且近似等分的 Glance 真实参考实现。示例结论为“每次发布带来的情绪”，副标题已经把图例、单位或时间口径写在图旁：复盘中标记的情绪反应 · 2026 年上半年

技术档案

项目 约定
数据形状 单变量分类计数，≤8 类且近似等分
场合 门面/封面
读者时间 <10s
渲染引擎 ECharts（暗卡）
交互与动效 滚入视野初始化，点击图表重播；保留原 gallery 的 tooltip 与动画
示例来源行 PETAL ROSE · MONO-DEMO · TEAM RETRO BOARD

实现与使用边界

  • 页面直接复用 gallery 中 “How releases made us feel” 的卡片结构和同名渲染块，没有按截图重新绘制。
  • 标题、副标题、图形、来源行四件套保持原样；数据编码、比例关系、灰阶和动画节奏由原实现决定。
  • 使用时只替换数据与文案，并保持“单变量分类计数，≤8 类且近似等分”这一数据契约；若数据本体改变，应回到总目录重新选型。
  • 颜色限于 Mono 灰阶，面积编码继续使用平方根换算；柱长、位置与角度编码不得断轴或视觉夸大。

模板来源：Lieflat Charts G2 Petal Rose，真实骨架取自 templates/glance-gallery.html 的 “How releases made us feel” 卡片与对应渲染块。
