Broken LOTR Example

[abhishektiwari]

Running LOTR example (Raphtory/examples/py/lotr ) using Python 3.11.4 with raphtory==0.6.1. Example worked after several changes based on latest API documentation.

1

Code Block:

graph = Graph(1)

**Error:**
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[1], line 7
      5 structure_file = "lotr.csv"
      6 properties_file = "lotr_properties.csv"
----> 7 graph = Graph(1)

TypeError: Graph.__new__() takes 0 positional arguments but 1 was given

2

Code Block:

print("Number of edges: %i" % len(graph.edges))

Error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[30], line 5
      3 print("Number of vertices: %i" % len(graph.vertices))
      4 print(graph.edges)
----> 5 print("Number of edges: %i" % len(graph.edges))

TypeError: object of type 'builtins.Edges' has no len()

Example should be using graph.count_edges()

3

Code Block:

with open(properties_file, 'r') as csvfile:
    datareader = csv.reader(csvfile)
    for row in datareader:
        graph.add_vertex_properties(row[0], {"race": row[1],"gender": row[2]})

Error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[28], line 4
      2 datareader = csv.reader(csvfile)
      3 for row in datareader:
----> 4     graph.add_vertex_properties(row[0], {"race": row[1],"gender": row[2]})

AttributeError: 'builtins.Graph' object has no attribute 'add_vertex_properties'

Hi @abhishektiwari - as mentioned in #1332, since creating the documentation on raphtory.com this examples folder has become more of a test space than explicit using facing examples. I shall tidy this up today.
