The d3.randomLogNormal() function is used to generate the random number based on the log-normal function.
Syntax:
d3.randomLogNormal(mu,sigma);
Parameters: This function accepts two parameters as mentioned above and described below:
- mu: It is the expected value of the random variable.
- sigma: The number is generated with a given standard deviation called sigma.
Returns: It returns a function.
Note: If mu and sigma is not given then mu is equal to 0 and sigma to 1 by default.
Below given are a few examples of the above function.
Example 1: The output may be different each time the function is executed.
