To create an Investigator HD Wallpaper using vector graphics, we can utilize the @mapbox/vector-tile library. Here's a brief snippet to get you started:

import { VectorTile } from '@mapbox/vector-tile';

// Load your vector tile data
const vectorTile = new VectorTile('your-vector-tile-data');

// Create an image element
const img = document.createElement('img');
img.src = data:image/png;base64,${vectorTile.toPng()};

// Set the image as the wallpaper
document.body.style.backgroundImage = url(${img.src});

This code snippet assumes you have your vector tile data in a format that can be loaded by the library. You'll need to replace 'your-vector-tile-data' with the actual data or URL of your vector tile.

Keep in mind that this is just a basic example, and you may need to adjust it according to your specific requirements and the structure of your vector tile data.
