What is a sankey graph?

A visualization that represents the flow of data or resources between different entities. It uses arrows of different widths to show the quantity or proportion of flow between nodes.

A visualization that's divided into sectors, or 'slices,' to represent categorical data. Each slice corresponds to a specific category or group, and the size of each slice represents the proportion or percentage that category contributes to the whole.

A visualization that uses line segments to display trends and changes over time. It is a powerful visualization tool used to analyze and understand the relationship between variables.

Explanation: What is a sankey graph?


Explanation: A Sankey graph is a visualization that represents the flow of data or resources between different entities, making **option A** the correct answer. It employs arrows of varying widths to depict the quantity or proportion of flow between nodes, effectively illustrating the dynamics of the system being analyzed. Unlike the other options, which describe different types of visualizations such as pie charts, line graphs, or area charts, a Sankey graph is specifically tailored to display flow relationships. This characteristic makes it particularly useful for understanding processes involving transfers or transformations of resources, such as energy flows in a system, migration patterns, or financial transactions. Therefore, option A accurately describes the essential features and purpose of a Sankey graph, distinguishing it from other types of visualizations.
