The graph shows this blog posts relationship in term of similarity.
|
||||
Each node in the graph is a post, two nodes are connected by an edge if
|
||||
they share some degree of similarity (weighted by edge thickness and edge distance).
|
||||
A large edge thickness and/or short edge distance shows a strong similarity between
|
||||
the two connected nodes.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Nodes are arranged by force which is modelled by content similarity.
|
||||
The more similar is the nodes content, the stronger is the force between them.
|
||||
Therefore, nodes that share similar topic will tend to group themself together in a cluster.
|

Navigate the blog by hovering the mouse on a node and following the node relationship
|

(edges) to find your interesting topic.
