As the title says I need .csv with coordinates of the world's continents. All I can find on the Internet are coordinates of world cities, which is not exactly what I am searching for. I want to make a map like the one attached below.   [![enter image description here][1]][1] Does anyone knows any good source to get such a file?

I will give a map of what I am currently running with.
1. I have found a .csv file with world countries. The file contains the longitudes and latitudes of those countries.
2. My JS program gets information about those positions and draws them as small points. I get something like this:

That's why I am looking for a .csv file with that kind of coordinates.
