Example
Draw a rectangle filled with a radial/circular gradient:
JavaScript:
const canvas = document.getElementById("myCanvas");
const ctx = canvas.getContext("2d");
// Create Radial
const grd = ctx.createRadialGradient(75, 50, 5, 90, 60, 100);
grd.addColorStop(0, "red");
grd.addColorStop(1, "white");
// Draw a filled Rectangle
ctx.fillStyle = grd;
ctx.fillRect(10, 10, 150, 100);
