How can I draw a circle on a JavaScript canvas? I want to be able to set the circle's position, radius, and color.
You can draw a circle on a JavaScript canvas using the `arc()` method. Here's an example code snippet that demonstrates how to draw a circle on a canvas with a specific position, radius, and color:

```javascript
// Get the canvas element
const canvas = document.getElementById('myCanvas');

// Get the 2D context of the canvas
const ctx = canvas.getContext('2d');

// Set the position of the circle
const x = 100; // X coordinate
const y = 100; // Y coordinate

// Set the radius of the circle
const radius = 50;

// Set the color of the circle
const color = 'blue';

// Begin the path
ctx.beginPath();

// Draw the circle
ctx.arc(x, y, radius, 0, 2 * Math.PI);

// Set the fill color
ctx.fillStyle = color;

// Fill the circle
ctx.fill();

// End the path
ctx.closePath();
```

In the above code, we first get the canvas element and its 2D context. We then set the position, radius, and color of the circle. We begin the path, draw the circle using the `arc()` method, set the fill color using the `fillStyle` property, fill the circle using the `fill()` method, and finally end the path using the `closePath()` method.
