The function create_graph_from_dataframes in the hana_ml.graph.factory module creates a HANA Graph workspace based on an edge and a vertices dataframe, with parameters to specify the connection context, vertices and edges dataframes, workspace name, schema, edge source and target columns, edge and vertex key columns, and various optional parameters for object type, dropping existing tables, allowing bigint, forcing tables and workspace, replacing, geo columns, and spatial reference system id.

Here is the executable code template based on the provided help doc:

```python
import hana_ml
from hana_ml.dataframe import ConnectionContext
import pandas as pd

# Create a connection to the SAP HANA system
connection_context = ConnectionContext(address='<address>', port='<port>', user='<user>', password='<password>')

# Load vertices and edges data from csv files
v_pdf = pd.read_csv("nodes.csv")
e_pdf = pd.read_csv("edges.csv")

# Create a HANA Graph workspace based on an edge and a vertices dataframe
hg = hana_ml.graph.factory.create_graph_from_dataframes(
    connection_context=connection_context,
    vertices_df=v_pdf,
    vertex_key_column="guid",
    edges_df=e_pdf,
    workspace_name="test_factory_ws",
    schema=None,
    edge_source_column='from',
    edge_target_column='to',
    edge_key_column=None,
    object_type_as_bin=False,
    drop_exist_tab=True,
    allow_bigint=False,
    force_tables=True,
    force_workspace=True,
    replace=False,
    geo_cols=[("lon", "lat")],
    srid=4326
)

# Print the created HANA Graph
print(hg)
```

Please replace `<address>`, `<port>`, `<user>`, and `<password>` with your actual SAP HANA system details. Also, make sure that the csv files "nodes.csv" and "edges.csv" are in the correct path.
