Cost Network Corridors

Hi, I would like to visualize cost corridors between a country and its recipient, something saturated and close to the one below (though on a world map):

At the same time, I would like to resize the lines, so that I could see which connection between two countries (let's say of 15k $) is more important to me than a 1$ connection, for example. Of course, the map should be flexible so I could choose my country and see how the costs have been spread between it and other countries around the world.

Is this somethign which I could create now on my own in Power BI?

Thanks, Atanas
