How to List Parent Term Links for Custom Taxonomy With & Without Children?

Here is some basic setup for the function that MavBzh mentioned.

<?php
$args = array(
    'title_li'          => '',
    'taxonomy'          => 'industry',
    'show_option_none'  => '',
);
?>

<ul><?php wp_list_categories( $args ); ?></ul>
