I am struggling to find a good workflow or tutorial that would link elements from rows with latitude and longitude on top of a geographical map.
For example, I have a table with lat+lon of London - New York - Tokyo. I would like to project the cities as nodes, and connect these 3 cities into a triangle (or connect each of the nodes with every other one).
| London lat | London lon | NY lat | NY lon | Tokyo lat | Tokyo lon Row0 | 51.51830479339951 | -0.12838351032819217 | 40.644803122358255 | -73.78124748038013 | 35.68149908918224 | 139.76704524135576
At the end, I would like to create a map like this: http://www.martingrandjean.ch/wp-content/uploads/2016/05/airports-map.png
Many thanks in advance!
