Newsmakers on the map is a design for a widget or html module that tracks the hot topics in news based on geographic locations. You mouse over or click on a particular region on the map to see the people that are getting the most coverage by the press in that region. You can then select one of those topics below the map and see the top 4 headlines from the sources in that region writing about that person.

Here is a design for a smaller version that can be developed as a grabbable widget.

Read more below to see what methodologies and API calls you will need to implement this design.
This is still an idea, but if you would like to give it a life - let us know.
The most important DayPI feature that enables the implementation for this design is Source Filtering. Trick is to have source filters for each geographic region that you want to highlight on the map.
Once you have the list of sources in each source filter, you can use the Source API Call (source_getTopics) to get the list of topics that sources in that region are writing about. Once the user selects a particular topic, you can call topic_getRelatedStories with the source_filter_id for that region to get the top 4 headlines for that topic published by sources in that region.
