This example displays a histogram from data generated with the Numpy library in Python. Typical code sample:
>>> import numpy as np
>>> count, division = np.histogram(d.price)
One might use a script to generate a number of histograms from a rather involved dataset, and view them later with D3.
Original code from Bostock’s Histogram was modified to 1) read from a JSON file, 2) prepare the displayed data structure, and 3) add a title.
The title is placed with knowledge of the data set. It would be useful to extend the example to place the title in white space given a heuristic.
