D3py是一個基于D3的Python繪圖庫。d3py的目的是提供一個簡單的方法將來自命令行或簡單的腳本數據畫到瀏覽器窗口。

import d3py
import pandas
import numpy as np

some test data
T = 100
this is a data frame with three columns (we only use 2)
df = pandas.DataFrame({
    "time" : range(T),
    "pressure": np.random.rand(T),
    "temp" : np.random.rand(T)
})
build up a figure, ggplot2 style
instantiate the figure object
fig = d3py.PandasFigure(df, name="basic_example", width=300, height=300)
add some red points
fig += d3py.geoms.Point(x="pressure", y="temp", fill="red")
writes 3 files, starts up a server, then draws some beautiful points in Chrome
fig.show() </pre>
