I recently put together a straightforward canvas text rotation demonstration on CodePen. The focus here is solely on showcasing rotation, without any added animations.

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
drawGuideLines();
ctx.font = "normal 36px Courier New";
// Text without any rotation applied.
ctx.strokeStyle="black";
ctx.fillText("SAMPLE TEXT no rotation",100,100);
// Adding an extra character at the beginning will shift the rest of the text to the right.
// Rotation of 0 degrees.
ctx.fillStyle="red";
ctx.save();
ctx.translate(100,200);
ctx.rotate(0 * Math.PI / 180);
ctx.fillText("0 deg rotation SAMPLE TEXT",0,0);
ctx.restore();
// Rotation of 90 degrees.
ctx.fillStyle="blue";
ctx.save();
ctx.translate(700,100);
ctx.rotate(90 * Math.PI / 180);
ctx.fillText("90 deg rotation SAMPLE TEXT",0,0);
ctx.restore();
// Rotation of 180 degrees.
ctx.fillStyle="green";
ctx.save();
ctx.translate(600,300);
ctx.rotate(180 * Math.PI / 180);
ctx.fillText("180 deg rotation SAMPLE TEXT",0,0);
ctx.restore();
// Rotation of 45 degrees.
ctx.fillStyle="purple";
ctx.save();
ctx.translate(100,400);
ctx.rotate(45 * Math.PI / 180);
ctx.fillText("45 deg rotation SAMPLE TEXT",0,0);
ctx.restore();
