private Point findClosestCluster(List<Point> markers, Point point) {
    if (markers == null || markers.isEmpty()) {
        return null;
    }

    Point closest = null;
    for (Point candidate : markers) {
        double dist = distanceSquared(candidate, point);
        if (dist < minDistSquared) {
            closest = candidate;
