Interpolating a string

In some cases, you might need to interpolate numbers embedded in a string; perhaps a CSS style for font, for example.

In this recipe, we will examine how you can do that using D3 scale and interpolation. However, before we jump right into string interpolation, a bit of background knowledge on interpolator is due, and the following section will cover the basics of what interpolation is and how D3 implements interpolator functions.


In the first three recipes, we went over three different D3 scale implementations; now it is time to delve a little deeper into D3 scales. You are probably already asking the question, How do different scales know what value to use for different inputs? In fact, this question can be generalized through the following definition of interpolator:

We are given the values of a function f(x) at different points x0, x1, ... ,xn. We want to find approximate values of the function f(x) for "new" x's that lie between these points. This process...
