• axis: the axis to rotate around

Below program illustrates the rotate() function in p5.js:
Example-1:

function setup() {

    // Create Canvas of given size
    createCanvas(380, 170);
}

function draw() {

    // Set the background color
    background(220);

    strokeWeight(12);

    //set strokeJoin function
    strokeJoin(ROUND);

    // rotation function
    rotate(PI / 10.0);
    line(20, 30, 200, 30);
    line(200, 30, 200, 100);
    line(200, 100, 20, 30);
}

Output:

Example-2:

}

function draw() {

    // Set the background color
    background(220);

    strokeWeight(12);

    // rotation function
    rotate(PI / 7.0);
    textSize(30);
    text("GeeksForGeeks", 50, 50);
