How to show search results on a timeline tool?

I have a node type which has a required datetime field for each node.

I need to display search results of this node type on a timeline tool instead of Drupal's default list of results.

I understand Drupal's search-result.tpl.php and some preprocessor functions,

but I dont know where to start and how Drupal can meet my need.

I am still learning Drupal. I understand I will do the detailed work, but I really would like to hear from people here

regarding directions, ideas, and thought process.

Thanks so much for any input.

All the best.
