Influence Charts are important for every spreadsheet user

An influence chart, in simple terms, is a map of all the elements and their connections in the model.

In the spreadsheet context, an influence chart is a diagram of all the values, formulas and their connections in the spreadsheet.

An influence chart is very important for spreadsheet design, understanding and error detection.

An influence chart is as important as a Google map when you are exploring a new city. Without a map, you see only whatever is near to you. With a map, you get an overview of the city, and you can decide where you want to go.

Just like a good map provides an overview of the city and the details, an influence chart provides an overview of the spreadsheet as well as the details.

This Youtube video provides a good explanation of influence charts (also called influence diagrams):
