## What is FunctionVisualizer?

函数可视化生成器是一款简洁强大的数学绘图工具，让你的 iPhone 秒变图形计算器。

■ 四种绘图模式
· 一元函数：同时绘制两个函数，自动解析求解交点并标注精确坐标；
· 极坐标：支持心形线、玫瑰线、螺线等 r=f(θ) 曲线；
· 参数曲线：x(t)、y(t) 自由定义，轻松画出李萨如曲线、圆与椭圆；
· 三维曲面：z=f(x,y) 以 jet 色带按高度着色，坐标盒子与刻度清晰，支持拖拽旋转。

■ 灵活调节
自定义函数定义域，拖入 a/b/c 参数滑动调节实时预览，白底网格、双函数不同颜色区分，交点一目了然。

■ 便捷体验
一键截图保存到相册，随手记录函数图像，适合学生、教师与工程人员日常查图与验证。
