csv file with latitude and longitude values

I hope my question is understandable:
I have a csv file with InSitu observations that I want to display in paraview along with results from our operational ocean model and some topography. The csv file contains latitude and longitude values ​​(as decimal) and temperature. Is it possible to read a csv file in paraview with latitude and longitude values, or do I need to convert them to paraview’s native map projection (“x coord”, “y coord”). And then, what is paraview’s native map projection?

Kindly regards,
Yvonne Gusdal
