A Scientific Example

The following code visualized typical data used in "data analytics."



In [ ]:

    
import numpy as np
from scipy.spatial import ConvexHull
points = np.random.rand(30, 2)   # 30 random points in 2-D
hull = ConvexHull(points)



In [ ]:

    
from bokeh.io import output_notebook
from bokeh.plotting import figure, show  # this _may_ have already been imported above



In [ ]:

    
output_notebook() # again, this may have been called already



In [ ]:

    
f = figure()



In [ ]:

    
f.circle(points[:,0],points[:,1], color='red')



In [ ]:

    
# Warning! Loop ahead!
for simplex in hull.simplices:
    f.line(points[simplex, 0], points[simplex, 1])



In [ ]:

    
show(f)
