Starting off with the simplest visualization to implement. The featured image acts as both a Placeholder for the visualization and a Thumbnail for the product.
To set the visualization, navigate to Settings then under Featured image either Drag & Drop or click and select your desired image.

Navigating to Design, you will see that the Featured image has been set in the Media panel within the canvas.
