Confused about input-sum-value and output-sum-value

[oceanumeric]

In the docs - node appearance part here
I am not sure what does input and output mean?

input-sum-value: Colors/sizes nodes by the sum across input-only records in the value column
output-sum-value: Colors/sizes nodes by the sum across output-only records in the value column

input means source and output means target?

Why set sum? Since I am not sure the meaning, also could not get the case when do we need this.

Thanks :)

Hello, @oceanumeric! The input-sum-value option calculates the sum of values by value column from all the input links of the node (e.g. link records where this node is a target). Similarly, the output-sum-value option calculates the sum of values from all the output links (link records where the node is a source).

By visually representing the cumulative value associated with the nodes, you can easily identify nodes with higher or lower cumulative values based on their input or output connections.

This feature can be particularly useful in exploring transactions or networks where you want to identify nodes that have a high input value but do not have a corresponding output value or vice versa. For example, in the context of wallets, you can use this to find wallets that receive a significant amount of funds but have few outgoing transactions, which may indicate an anomaly within that network.

Hope this answer helps you figure it out. ☺️
