"Extra" lines in OrgChart

[Jackie McHenry]

What could be causing the "extra" lines in my orgChart?  Any way to remove them?

<script>

  google.charts.load('current', {packages:["orgchart"]});

  google.charts.setOnLoadCallback(drawChart);

  

  function drawChart() {

  var data = new google.visualization.DataTable();

  data.addColumn('string', 'Name');

  data.addColumn('string', 'Manager');

  data.addColumn('string', 'ToolTip');

  

  // For each orgchart box, provide the name, manager, and tooltip to show.

  data.addRows([

    @php

    

      $rowcount = count($coordinator_array);

      //Now make the tree

      for($a=0;$a<$rowcount;$a++){

        $first_name = str_replace(array("'", "\"", "&quot;"), "", htmlspecialchars($coordinator_array[$a]['first_name'] ) );

        $last_name = str_replace(array("'", "\"", "&quot;"), "", htmlspecialchars($coordinator_array[$a]['last_name'] ) );

        

        echo "[{v:'" . $coordinator_array[$a]['id'] . "', f:'". $first_name . " " . $last_name . "<br>" . $coordinator_array[$a]['position_title'];

        

        if ($coordinator_array[$a]['sec_position_title']!="")

          echo " / " . $coordinator_array[$a]['sec_position_title'];

        

        echo "'},'";

        if ($coordinator_array[$a]['report_id']==366 && $cord_pos_id == 7)

          echo "'";

        else if($coordinator_array[$a]['report_id']==1 && $cord_pos_id != 7)

          echo "'";

        else

          echo $coordinator_array[$a]['report_id'] . "'"; 

        

        echo ",''],\n"; // '" . $coordinator_array[$a]['chapter_list'] . "'],\n"; 

      }

    

    @endphp 

  ]);

  

  // Create the chart.

  var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));

  // Draw the chart, setting the allowHtml option to true for the tooltips.

  chart.draw(data, {allowHtml: true, allowCollapse: true, size: 'small'});

  }
