Could you please give me more details of how you want to embed chart? Do you have any difficulty or is there any error show? You may view our Googe Gauge Chart example.
Our gauge chart work on php so your mainpage should have php extension: dashboard.php for example.
You can add this to your main page
<?php \koolreport\widgets\google\Gauge::create(array( "dataSource"=>array( array("label"=>"Goal","value"=>80), ), "columns"=>array( "label", "value"=>array( "suffix"=>"%", ) ) )); ?>
