Walkthrough

The changes to cognee/shared/utils.py introduce advanced graph visualization capabilities. The module now supports enhanced graph rendering using Bokeh, with new functions for converting graphs to serializable formats, generating layout positions, assigning node colors, embedding logos, and creating styled network visualizations. These modifications provide more sophisticated tools for graph manipulation and presentation, focusing on improving the visual and structural representation of graph data.

🐰 A Rabbit's Graph Tale 🌐

With Bokeh's brush and NetworkX might,
Our graphs now dance with colors bright
Logos embedded, layouts precise
A visual feast that looks so nice!
Graph magic brewing, code so keen 🎨

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

15-20: Avoid redundant or overshadowed imports.
These imports duplicate earlier imports (networkx as nx is already defined at line 9, for instance) and can confuse maintainers. Retain them at the top of the file in a single block to improve consistency and readability.

- import base64
- import networkx as nx
- from bokeh.io import output_file, save
- from bokeh.plotting import figure, from_networkx
- from bokeh.models import Circle, MultiLine, HoverTool, ColumnDataSource, Range1d
+ # Remove duplicates or move them to the top unified import section

228-230: Remove or restore the commented-out code.
This method is commented out entirely. If you no longer need sanitize_df, consider removing it altogether. Otherwise, please restore and maintain relevant tests.


259-269: Duplicate imports repeated here as well.
This block re-imports the same libraries (e.g., nx, base64) and redefines Bokeh components. Consolidate all imports at the top of the file to follow best practices and eliminate redundancy.

- import networkx as nx
- from bokeh.plotting import figure, output_file, show
- from bokeh.models import Circle, MultiLine, HoverTool, Range1d
- from bokeh.io import output_notebook
- from bokeh.embed import file_html
- from bokeh.resources import CDN
- from bokeh.plotting import figure, from_networkx
- import base64
- import cairosvg
- import logging

270-271: Avoid configuring logging at the library level.
Calling logging.basicConfig here can override users’ logging settings. Usually, this configuration belongs in the application’s entry point.

- logging.basicConfig(level=logging.INFO)
+ # Remove or relocate this to the application's main entry point or __main__ guard

300-306: Handle missing node attributes gracefully.
This function works as intended. However, if the node_attribute is missing, nodes default to "Unknown". Consider validating or logging a warning to handle unexpected node data.


308-332: Consider extracting large inline SVG into a separate file.
Storing the logo SVG inline can make maintenance difficult. Keeping the SVG in its own file could reduce clutter and allow quick updates if the logo changes.


436-472: Example usage is helpful; watch for repeated imports.
This section demonstrates the new functions well. However, remove redundant imports that already appear at the top.

🔇 Additional comments (4)
cognee/shared/utils.py (4)

293-298: Layout generation looks solid.
This code appropriately uses the provided layout function and returns a scaled dictionary of positions.


333-355: Styling logic is well-structured.
The usage of from_networkx and node radius calculations are clear. This approach is well-suited for Bokeh visualizations.


422-431: graph_to_tuple implementation looks appropriate.
It collects nodes and edges with attributes into lists. This approach is straightforward for serialization or partial transformations.


356-420: Combine tasks successfully; verify the fixed convert_to_serializable_graph.
The overall flow is good, but it depends on the correction of the logic bug in convert_to_serializable_graph. After fixing, ensure this function produces the intended result.

⚠️ Potential issue

Incorrect logic in convert_to_serializable_graph.
The code never transfers nodes/edges from networkx_graph into new_G. Iterating over new_G while it’s empty prevents any data from being copied.

Below is a sample fix ensuring new_G is properly populated:

 def convert_to_serializable_graph(G):
     (nodes, edges) = G
-    networkx_graph = nx.MultiDiGraph()
+    networkx_graph = nx.MultiDiGraph() if isinstance(G, nx.MultiDiGraph) else nx.Graph()
     networkx_graph.add_nodes_from(nodes)
     networkx_graph.add_edges_from(edges)

-    new_G = nx.MultiDiGraph() if isinstance(G, nx.MultiDiGraph) else nx.Graph()
-    print(new_G)
-    for node, data in new_G.nodes(data=True):
+    new_G = nx.MultiDiGraph() if isinstance(networkx_graph, nx.MultiDiGraph) else nx.Graph()
+    for node, data in networkx_graph.nodes(data=True):
         serializable_data = {k: str(v) for k, v in data.items()}
         new_G.add_node(str(node), **serializable_data)
-    for u, v, data in new_G.edges(data=True):
+    for u, v, edge_data in networkx_graph.edges(data=True):
         serializable_data = {k: str(val) for k, val in edge_data.items()}
         new_G.add_edge(str(u), str(v), **serializable_data)
     return new_G
