protected function getData(): array
    {
        $commentTags = CommentTag::with('comments')->get();

        $commentTags->loadCount('comments');

        foreach ($commentTags as $commentTag) {
            return [
                'datasets' => [
                    [
                        'label' => 'Commnets Tags Usage',
                        'data' => [$commentTag->comments_count],
                    ],
                ],
                'labels' => [$commentTag->name],
            ];
        }
