This is an example of how to display rankings on Shopify's collection pages (https://store-dojo.com/products/2024-07-30), and although it's a bit of a stretch, it allows you to display rankings in the "Featured Collections" section in the same way, simply by editing from the theme editor.
Example of setting up Shopify's theme "Dawn" to display rankings in the "Featured Collection" section using only the theme editor without "editing the code".

[(For the Dawn theme) How to set it up] Add a customized Liquid section to the template where you want to place the section (in this example, the top page) and insert the code.
