The randomUniform() function in D3.js is used to return a random number in a particular range. The range is to be defined by the max and min number.
Syntax:
d3.randomUniform(min, max);
Parameters: It takes two parameters as mentioned above and described below:
- min: It is the minimum value of the random number possible.
- max: It is the maximum value of the random number possible.
Return Value: It returns the random number between the given range.
Note: The output of the code will be different each time it is executed.
Below given are a few examples of the above function.
Example 1: When min and max ranges are given.

<!DOCTYPE html> < html lang = "en" > < head > < meta charset = "UTF-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1.0" > </ head > < body > <!-- Fetching from CDN of D3.js --> < script type = "text/javascript" </ script > < script > // Random number between 1 and 10 console.log(d3.randomUniform(1, 10)()) console.log(d3.randomUniform(1, 10)()) console.log(d3.randomUniform(1, 10)()) console.log(d3.randomUniform(1, 10)()) console.log(d3.randomUniform(1, 10)()) console.log(d3.randomUniform(1, 10)()) console.log(d3.randomUniform(1, 10)()) </ script > </ body > </ html > |
Output:
Example 2: When min and max are equal
HTML
<!DOCTYPE html> < html lang = "en" > < head > < meta charset = "UTF-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1.0" > </ head > < body > <!-- Fetching from CDN of D3.js --> < script type = "text/javascript" </ script > < script > // Random number less then 10 and // greate than 0 console.log(d3.randomUniform(10)()) // Random number equal to 10 console.log(d3.randomUniform(10, 10)()) </ script > </ body > </ html > |
Output: The output may be different every time the code is executed.
