不等式几何作图函数图像
①本范例演示如何通过 GeoGebra 将数字分类为整数、小数或有理数；②涉及核心数学概念包括整数、有理数、分类、比较；③作图要点：使用 Segment, Circle, Random, Sum, Text, Polygon 等命令创建图形和文本，通过 point1, center, circle1, circle2, circle3 等对象展示分类过程；④适合初中及以上数学教学，用于理解和应用有理数分类知识。

AI 绘图提示语参考

要画一个图形，用于展示有理数的分类。图形中包含线段、圆和文本，用于表示整数、有理数和整数的区域。构造顺序是先创建圆和线段，然后生成随机数，最后将数字拖动到相应的区域。图形旨在帮助学生理解分类概念。
