# What type of graph is this? What is this type of graph called? I find this graph across some website but I am unable to recall.

Following are the features of this graph:

1. Nodes are connected to a central node, indicating layers of information.
2. Clicking on a node gives information about that node.

Can someone provide some use cases and reference for this graph?

The term is Force directed graph.

Here's an example of an ontology, where the side panel displays selection (circle in red) details: ## Hyperbolic Tree

Based on the info provided, this appears to be a hyperbolic tree. Characteristics include:

• central node
• exponential node increases A hyperbolic tree defines a graph drawing method inspired by hyperbolic geometry.

Displaying hierarchical data as a tree suffers from visual clutter as the number of nodes per level can grow exponentially. For a simple binary tree, the maximum number of nodes at a level n is 2n, while the number of nodes for larger trees grows much more quickly.

Drawing the tree as a node-link diagram thus requires exponential amounts of space to be displayed.

quote and example from the data viz project.

The interactivity of clicking to get information about a specific node is simply a good practice for any digital info visualization.

I always knew this as multinode graph (in Graph Theory) or Network Diagram in DataViz
