What is a Sankey Diagram and Why Use SankeyMATIC?

Alright, first things first: What is a Sankey diagram? Simply put, it's a type of diagram that visualizes the flow of something – it could be energy, money, people, or anything else you can think of – from one set of things to another. The width of the arrows in the diagram represents the quantity or value of the flow. Wider arrows mean more of whatever is flowing, making it super easy to spot the biggest movers and shakers in your data. It's like a visual story, guiding your eyes through the data to show you the important stuff. These diagrams are named after Irish Captain Matthew Henry Phineas Sankey, who used them to visualize the energy efficiency of a steam engine in 1898 – pretty neat, huh?

Getting Started with SankeyMATIC: A Step-by-Step Guide

Okay, let's get down to the nitty-gritty and walk through how to actually use SankeyMATIC. Don't worry, it's easier than it sounds, and I promise you'll be creating diagrams in minutes! First, head over to the SankeyMATIC website (just Google it, you'll find it). The homepage is clean and simple, with a large text box ready for your data.

Inputting Your Data

The most important part is getting your data in the right format. SankeyMATIC uses a specific format, but don't worry, it's pretty straightforward. Each line of your data should follow this structure:

Source [tab or space] Target [tab or space] Value

  • Source: This is where the flow begins.
  • Target: This is where the flow ends.
  • Value: This is the quantity or amount of the flow. It can be a number (like the amount of money or the number of people).

Let's say you want to visualize where your monthly income goes. Your data might look something like this:

Salary	Rent	1000
Salary	Groceries	400
Salary	Savings	300
Rent	Landlord	1000
Groceries	Supermarket	400
Savings	Bank	300

Each line represents a transaction: your salary goes to rent, groceries, and savings, which in turn go to the landlord, supermarket, and bank. The number at the end tells you how much money goes where. You can use either tabs or spaces to separate the source, target, and value. Make sure you get the tab/space right, or the tool won't work.

Copy and Paste Your Data

Once your data is formatted correctly, simply copy and paste it into the text box on the SankeyMATIC website. Once pasted, the magic begins! The tool will process your data and generate a visual representation of your flow. You should immediately see a Sankey diagram take shape.

Customization Options

SankeyMATIC also has a few customization options to tweak your diagram and make it look just right. You can adjust the colors of the flows and the labels, the font size, and even the background color to match your needs. To make changes, just type the following commands into the data box (in separate lines):`

  • color: source, target, color to change the color of a specific flow or a label. For example, to make your
