Display 3-D Molecule Structure with 3Dmol.js
Q
How to display a 3-D molecule structure with 3Dmol.js?

A
If you have a 3-D molecule structure stored in SDF format,
you can follow these steps to load and display it with the 3Dmol.js library.
1. Create an HTML file, Display-Molecule.html, with the following code. The molecule's SDF data is hidden in a <textarea> tag.
<html><head>
<script src="/3Dmol-min.js"></script>
<style>
.mol-container {width: 400px; height: 400px; position: relative;}
</style>
</head>
<body>
<div id="container-01" class="mol-container"></div>
<textarea id="molecule" style="visibility:false">

$(function() {

let config = { backgroundColor: 'grey' };
let viewer = $3Dmol.createViewer( element, config );
var rec1 = viewer.addModel($('#molecule').val(), "sdf");
rec1.setStyle({stick:{color:'lightgray', opacity:'1.0'}, sphere:{color:'gray', radius: 0.4}});
viewer.addLabel("Aromatic", {position: {x:2.6, y:0.75, z:0.35}, backgroundColor: 0x800080, backgroundOpacity: 0.8});
viewer.zoomTo();
viewer.render();
});
</script>
</body></html>
2. View the HTML document through your Web server: http://localhost/Display-Molecule.html. You see the 3-D molecule structure displayed. You can room in and rotate it with your mouse.
