    // Update the data to a new position based on the animation timestamp. The
    // divisor in the expression `timestamp / 1000` controls the animation speed.
        Math.cos(timestamp / 1000) * radius,
        Math.sin(timestamp / 1000) * radius

    // Ensure it's added to the map. This is safe to call if it's already added.

    // Request the next frame of the animation.

// Start the animation.
