Difference chart code
Explanation
Lines 98-105: The observant D3.js reader will have noticed that the setting of the y domain has a large section commented out.
That’s because I want to be able to provide an ideal way for the graph to represent the data in an appropriate range. But because we are using the basis smoothing modifier and the data is “peaky,” there is a tendency for the y scale to be fairly broad and the resultant graph looks a little lost:
Alternatively, we could remove the smoothing and let the true data be ...
