Adding data labels (annotations?) to Google Charts (Visualizations API) drawn from a query

I'm creating a line chart by querying data entered into a Google Sheet, and I need to add data labels, i.e. the little numbers next to the points on the chart. I found plenty of documentation on how to do this with charts drawn from a manually entered data-table, but not from a query to a Google Sheet. Please help.

google.charts.load('current', {'packages':['corechart', 'line']}); 
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
var query = new google.visualization.Query(
  'URL'
);
query.setQuery('SELECT A, B OFFSET 0'); //select specific cells from the table
query.send(handleQueryResponse);
}

function handleQueryResponse(response) {
if (response.isError()) {
  alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
  return;
}

var data = response.getDataTable();
var options = {
  title: '',
  height : 250,
  width : '100%',

    }
 var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
