Linking circles to Categories

Hello,

I have read some discussions about linking circles to categories instead of posts.

Caroline said as below,

You could probably create a child theme with a custom page template that uses one of these functions, then style the output to look like the circles by copying the styles from the parent theme’s style.css:

https://codex.www.ads-software.com/Template_Tags/wp_list_categories

Is there any other way that alreay answered and I missed or how can we apply this solution.

Thanks,
Selin.
