The Extended Graph plugin can visualize various statistical metrics by adjusting node sizes and colors based on vault analytics. This feature helps identify patterns and important elements in your vault's structure.

You can choose the size of a file node with a property. Number values found for the specified property will be used as the base size instead of the default size (100).

Nodes can be sized or colored based on the following metrics:

Basic Metrics

• Number of backlinks
• Number of forward links
• Number of unique forward links
• File name length
• Number of tags
• Time since file creation
• Time since last modification

Graph Analytics

• Betweenness centrality: Measures how often a node acts as a bridge between other nodes
• Closeness centrality: Indicates how close a node is to all other nodes
• Eccentricity in the connected graph: The maximum distance from this node to any other node
• Degree: Total number of connections
• Eigenvector centrality: Measures node importance based on the importance of its neighbors
• Hub centrality (from HITS): Indicates how well a node points to authority nodes
• Authority centrality (from HITS): Indicates how well a node is pointed to by hub nodes
• Topological propagation: Measures how many nodes are connected with forward links (directly and indirectly)

• Number of occurences: Count the number of time a link exists in a node

The following metrics require the Graph Analysis plugin to be enabled. Please see the documentation of this plugin for more information.

• Adamic-Adar: Measures connection strength based on shared neighbors
• Bag of Words: Analyzes similarity based on note content (also requires NLP plugin)
• Clustering Coefficient: Measures how connected a node's neighbors are to each other
• Jaccard: Compares the overlap of connections between nodes
• Otsuka-Ochiai Coefficient (also requires NLP plugin)
• Overlap Coefficient: Measures the overlap between node neighborhoods
• Sentiment (also requires NLP plugin)
• Co-Citations: Measures how often two nodes are cited together

The Obsidian graph is oriented, meaning that links have a direction (from source to target). This impacts multiple statistics depending on graph analysis and edge orientations. If you want to reverse this and use a direction from target to source, enable this feature.

• Values are normalized relative to your vault's content
• Larger nodes/links indicate higher values for the chosen metric
• Statistics are not calculated in real-time, they are calculated when you open your vault or when you change the setting
