How to update front end data with node js?

I want to make a website that can display a plot with node.js. I also want to update the data every minute without refreshing the whole page. I am new to node.js and would like to learn how to use "get" request to update the data with a server.

Here I created a server in app.js:

    http.createServer(function(req, res){
    console.log('You are listening to port 3000');
    fs.readFile('./controllers/index.html', function(err, data){
    res.writeHead(200,{'Content-Type': 'text/html'});
    res.write(data)
    res.end();
  });
}).listen(3000);

If my index.html is:

<html>
<body>
<h1>My Datasets</h1>
<p>Some data plot</p>
</body>
</html>

and I want to change the data plot every minute. How do I make a request from the frontend and provide the required data with the server?

Thanks.
