Sankey Diagrams: An Underrated Gem of Data Visualization

Many tabular data analysis tasks can be interpreted as a flow between the source and a target.

Instead of manually analyzing tabular data, try to represent them as Sankey diagrams.

They immensely simplify the data analysis process.

For instance, from the diagram above, one can quickly infer that:

• Washington hosts flights from all origins

• New York only receives passengers from London

• Majority of flights in Los Angeles come from Dubai

• All flights from New Delhi go to Washington

Now imagine doing that by just looking at the tabular data.

1) It will be time-consuming
