①本范例演示如何使用表格数据创建直方图；②涉及的核心数学概念包括直方图、正态分布、线性回归、数列与级数、利率计算、四边形；③作图要点——从下方『构造摘要』提炼用到了Textfield, Polygon, Segment, Sequence, Vector, Sort, Element, If等GeoGebra命令/对象；④适合高中阶段数学教学或数据分析入门学习。

AI 绘图提示语参考

画一个直方图，包含一个表格输入数据，直方图由多个矩形组成，每个矩形的高度对应输入数据，底部在横轴上，矩形之间有间隔，横轴和纵轴有刻度标记，背景有网格线，整体展示数据的分布情况。
以上提示语为根据原始绘图命令整理而来，仅供参考。
