3D Stems

Usage 

from std.math import cos, sin

from dataviz import save, stem3d

def main() raises:
    # Illustrative readings taken around a circular track.
    var x = List[Float64]()
    var y = List[Float64]()
    var z = List[Float64]()
    for i in range(28):
        var t = Float64(i) * 0.224
        x.append(cos(t))
        y.append(sin(t))
        z.append(1.0 + cos(t * 3.0) * 0.6)

    var c = stem3d(
        x, y, z, title="Illustrative Readings Around a Track"
    )
    save(c, "docs/src/examples/out_stem3d.svg")
