Creating a airplane route and show on a map

Hi Everyone,

Simply put i have two geolocations that i have retrieved from the user and stored to the database. What i want to do now is create a circle around the first geolocation with the radius of the circle being the distance between the two geolocations. I have found a way to get that distance but no way of displaying it on a map. Is there any plugin that can help?

Something like this image:

Thank you in advance

Best,

Lino
