A Sankey diagram shows where things go: how a salary splits into rent, food and savings, how energy moves from sources to uses, how visitors move through a website. Each row of the table is one flow with three cells: where it comes from, where it goes and how much. Names that repeat are the same node, so Income can receive from Salary and Freelance and pass on to Housing, Food and Savings. The diagram draws every flow as a band exactly as wide as its amount.
There is nothing to arrange. Steps are placed in columns from left to right by how far they are from the start, every end point lines up in the last column, and the nodes in each column are ordered to cut down crossing bands. Each node is as tall as the larger of what flows in and what flows out, and the bands blend from the colour of their source to the colour of their target. With Values on, every node shows its total. A flow that would loop back to an earlier step is left out, and a note under the table says so.
Copy three columns from Excel or Google Sheets into the top-left cell, or drop a CSV file on the page. For a single path where people drop out step by step, the funnel chart maker is simpler; to show one total split into parts, try the treemap. Every type is on the chart maker.

One row per flow: a source, a target and an amount. Nodes are created from the names you type.
Either its amount is zero or not a number, its source and target are the same, or it points back to an earlier step and would make a loop.
Yes. That is what the diagram is for: a node collects everything flowing in and passes it on to all its targets.
