There is no need to edit any core files.

Copy bb-template/front-page.php to my-templates/front-page.php and then in that file find

<?php tag_heat_map(); ?>

and replace it with:

<?php tag_heat_map( 10, 30, 'px', 40); ?>

to generate a tag cloud of the top 40 tags where the smallest tag displays with a 10px font-size and the largest with a 30px font-size.

The first parameter is the size of the smallest tag, the second is the size of the largest tag, the third is what unit to use (’em’, ‘px’, ‘pt’, …) and the last is how many tags to show.
