Parse HTML input value to php over javascript file

From the code you’ve shown, it doesn’t look like you’re passing the input value along with your ajax request, you should add something like 

$.ajax({
   url : "/graph.php",
   type : "GET",
   data : {input : $('#subject').val()}, <-- added this
   success : function(data){

In order to be able to see the value in $_GET['input'] on the php side.

But there is another issue I believe, your ajax request is sent as soon as your document is ready ($(document).ready(function(){), but at that time your input is most likely going to be empty. You probably want to change it to $('form[name="form"]').on('submit',function(event){event.preventDefault(); ...}), assuming your form only does that one thing (display a graph according to the input)
