I ran across an online site that will take a list of addresses or locations and map them on a custom Google map. It is all free. The site is called Batch Geo located at https://batchgeo.com/ .
For example I took the DBE directory and created the following map:
What else could you map?
Employee names and addresses. Who lives near that job?
Job list. What jobs of mine are close to each other?
Suppliers list. Who is near that job?
