D3.js interpolateString() function Last Updated : 13 Feb, 2022 Comments Improve Suggest changes Like Article Like Report The intepolateString() function in D3.js is used to return the interpolator function between two strings. For each number in string "b" the function finds a number for it in string "a", then it returns the interpolation of these numbers using Number interpolator function, and the remaining part of string "b" is used as a template. Syntax: d3.intepolateString(a, b); Parameters: It takes two parameters: a: It is a string of characters and numbers.b: It is also a string of characters and numbers. Returns: It returns the interpolator function. Below given are a few examples of the above function.
