heres a good example

```auto
<!DOCTYPE html>
<html>
	<head>
		title>
    <script </script>
    
    <script>
      function updateLabels(x, y){
        var xLabel = document.getElementById('x-label');
        xLabel.innerHTML = 'X: ' + x;
        
        var yLabel = document.getElementById('y-label');
        yLabel.innerHTML = 'Y: ' + y;
      }
    </script>
		
		<script>
			function setup(){
				var canvas = createCanvas(200, 200);
        canvas.parent('sketch-div');
			}
			
			function draw(){
        background(32);
				fill(255);
				ellipse(mouseX, mouseY, 20, 20);
        
        updateLabels(mouseX, mouseY);
			}
		</script>
	</head>
	<body>
    <div id="sketch-div"></div>
    <p id="x-label"></p>
    <p id="y-label"></p>
	</body>
</html>

Heres a math equation displaying the universe in four-d it should show that there is something missing how can i enter this into a p5 physics generator of some sort

Please format all code posts on the forum by either:

1. highlight your code and using the \</\> button

or

1. using three tick marks ``` before and after your code

When you type html and raw code in your posts, it breaks your posts.

Instead, do it like this:

````auto
```
<em>my code</em>
<iframe>
```

````

so that we see it like this:

```auto
<em>my code</em>
<iframe>

```

…and not like this:

_my code_
