The d3.scalePow() function is used to create and return a new continuous scale. This scale has a specified domain and range. Generally, it acts as a linear scale but when used with exponent it works in a different way.
Syntax:
d3.scalePow([[domain, ]range]);
Parameters: This function accepts two parameters as mentioned above and described below.
- domain: This parameter always accepts two or more than two numbers.
- range: This parameter accepts a number or a string array.
Return Values: This function does not return anything.
Below examples illustrate the scalePow() function in D3.js:
