How can i put more details into GeoChart (lavacharts)

khill/lavacharts` Version 3.1

Hi, I'm trying to do a geo chart with LavaCharts, and I wanted to add more columns. Like I would like to have Country, Users, Description, Etc. (another column from the database). I did some code but when I refresh my page appears without the 'Country' label/text

the blade view, here you can see how my data/columns from database are, missing Country, and the description doesn't have a column, it just appears as a label.

Controller Code (chart creation code)

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Khill\Lavacharts\Lavacharts;
use App\Visitor;
class VisitorController extends Controller
{
    public function index(){
        $lava = new Lavacharts;

        $data = Visitor::select( "country as -1","description as 0","users as 1")->get()->toArray();



        $popularity= $lava->DataTable()
                    ->addStringColumn("Country")    
                    ->addStringColumn("Description")  
                    ->addNumberColumn("Users    ")      
                    ->addRows($data);

        $lava->GeoChart("Popularity", $popularity);

        return view("visitor",["lava"=>$lava]);
    }
}

(Controller)

Model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Visitor extends Model
{
    protected $fillable=['country','description','users'];
}

(Model)


blade: 
`
<div  id="visitor" style="width:80%;margin:0 auto;"></div>
<?=$lava->render("GeoChart","Popularity","visitor");?>
`
web.php:
` Route::get('/visitor', 'VisitorController@index')->name('visitor');`






If i do something like this :

  $popularity = $lava->DataTable();

            $popularity->addStringColumn('Country')
                ->addNumberColumn('Popularity')
                ->addStringColumn('Desc')
                ->addRow(array('Germany', 200,'asdad'))
                ->addRow(array('United States', 300,'asdad'))
                ->addRow(array('Brazil', 400,'asdad'))
                ->addRow(array('Canada', 500,'asdad'))
                ->addRow(array('France', 600,'asdad'))
                ->addRow(array('RU', 700,'asdad'));

The error is: Incompatible data table: Error: Table contains more columns than expected (Expecting 2 columns)×
