You didn not answer the question: Which javascript package do you expect to make the pie chart for you?
You seem to be missing anything that gets the data, $sth->execute() does not return any data. you need something like my $table = $sth->fetchall_hashref; to actualy get the data. That returns an array reference such that $table->[0] has the first row of data and $table->[0]{queue_name} has the value of the queue_name column in the first row. That in no way matches your attempts to use something like $TABLE_DATA{1}{'ENTRY'} as a variable name where 1 is taken as a key to the hash %TABLE_DATA and ENTRY is taken as key to the hash %{$TABLE_DATA{1}}.
