HI Team , in nebula studio can we only import csv files or we can connect to db directly and query the data in nebula studio? and i have graph data in gexf file which i made from networkx library , can it be imported in nebula graph?

Yes, using Nebula Studio, you can not only directly import CSV files into the Nebula graph database, but you can also connect Nebula Studio to your S3 to import CSV files. This means you need to first upload the CSV to the studio, and then import the CSV file into the database.
