In graph visualization, what would a layout be?

A lab is conducting a study on protein interactions. They have used the data to create a graph visualization.

In graph visualization, what would a layout be?
A . A single data point
B . A link between two data points
C . A dedicated algorithm that calculates the node positions
D . A collection of data points and links

Answer: C

Explanation:

A layout is a way of arranging the nodes and links of a graph visualization to convey meaningful information about the data. A layout is determined by a dedicated algorithm that calculates the node positions based on certain criteria, such as minimizing edge crossings, maximizing node spacing, or emphasizing clusters12. A layout can also be influenced by user interaction, such as zooming, panning, or dragging3.
