<!-- Answer -->
Here's a sample CSV file that contains both vertices and edges data:
```csv
name,age,city,source_name,target_name,date,weight
marko,29,Beijing,marko,vadas,2016-01-10,0.5
vadas,27,Hongkong,marko,josh,2013-02-20,1.0
josh,32,Beijing,peter,josh,2013-02-20,1.0
peter,35,Shanghai,marko,josh,2013-02-20,1.0
```
This CSV file includes vertex attributes (`name`, `age`, `city`) and edge
attributes (`source_name`, `target_name`, `date`, `weight`).
Here's a test example using this CSV file:
```java
@Test
public void testLoadVerticesAndEdges() {
ioUtil.write("edge_and_vertices.csv",
"name,age,city,source_name,target_name,date,weight",
"marko,29,Beijing,marko,vadas,2016-01-10,0.5",
"vadas,27,Hongkong,marko,josh,2013-02-20,1.0",
"josh,32,Beijing,peter,josh,2013-02-20,1.0",
"peter,35,Shanghai,marko,josh,2013-02-20,1.0"
);
String[] args = new String[]{
"-f", structPath("customized_schema/struct.json"),
"-s", configPath("customized_schema/schema.groovy"),
"-g", GRAPH,
"-h", SERVER,
"--batch-insert-threads", "2",
"--test-mode", "true"
};
PapayaDBDataLoader.main(args);
}
```
Ensure that your `struct.json` and `schema.groovy` files are correctly
configured to handle both vertices and edges, as previously discussed. This
test will load the data from the CSV file into your graph database, assuming
the schema is properly defined
