CSV file with longitude and latitude coordinates of continents borders

Question

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. 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: As you can see the contours of the continents such as Africa are barely visible. That's why I am looking for a .csv file with that kind of coordinates.

Answer 1

I think the answer is basically what Babel responded with. You could get the continents dataset online, no problem, in .gpkg, geoJSON (which might be usable by itself in your java code), or .shp file format and convert it to .csv using QGIS.

One note about getting a single landmass outline like the picture above (no country/continent borders) is that you will need to dissolve either A: all the countries' individual polygons from a country dataset or B: all of the continent's polygons from a continent dataset in order to not have border lines between them.
