Usage

from dataviz_mojo import nightingale
from dataviz_mojo.plot import save

def main() raises:
    var causes: List[String] = ["Zymotic disease", "Wounds", "Other"]
    var deaths: List[Float64] = [1857.0, 202.0, 97.0]

    var c = nightingale(causes, deaths, area=True)
    save(c, "docs/src/examples/out_nightingale.svg")

Args:
