triplot(x, y; kwargs...)
triplot(positions; kwargs...)
triplot(triangles::Triangulation; kwargs...)根据提供的位置或 三角测量 来自DelaunayTriangulation。jl．
地块类型
绘图类型别名 三联体,三联体 功能是 三联体,三联体.
例子：
A 三联体,三联体 绘制由任意点集生成的三角形网格。 输入数据可以是基于点的（如 散点,散点 或 线条)或一个 三角测量 从https://github.com/DanielVandH/DelaunayTriangulation.jl[DelaunayTriangulation.jl]。
