Title: Unlocking the Secrets of Sankey Charts: Visualizing Complex Data with Ease

Introduction :

Sankey charts have been increasingly popular in the field of data visualization and are widely used to visualize complex data effectively. These charts are particularly effective in showing relationships between different variables.

What is a Sankey Chart?

A Sankey chart, also known as a gantt chart, is a type of network diagram that displays quantities, rates, and functions of a process or a set of activities. It is designed to show the flow of activity, which is essentially the direction of data flow. It is most commonly used in fields like finance, engineering, and marketing.

In this article, we will explore the secrets of Sankey charts and how they can be used to visualize complex data in a way that is easy to understand.

Creating a Sankey Chart

Creating a Sankey chart can be done through a few different methods, depending on the specifics of the dataset you are working with. Here I will demonstrate how to create a simple Sankey chart using the R programming language and the networkDynamics package.

Here is the R code:

“`
library(networkDynamics)
library(ggplot2)

ggplot(data = structure(list(data = c(52L, 64L, 8L, 26L, 9L, 29L)),
by = c(“Name”, “Type”)),
aes(x = Name,
y = Type,
color = Type)) +
ggplot2::geombar(stat = “identity”) +
ggplot2::geomtext(data = structure(list(Name = c(“John”, “Jane”, “Bob”, “John”, “Jane”, “Bob”),
Type = c(52L, 64L, 8L, 26L, 9L, 29L)),
by = “Name”), aes(x = Name,
y = Type,
color = Type)) +
ggplot2::scalecolormanual(“Type”, values = c(“red”, “green”, “black”, “blue”, “green”)) +
ggplot2::scalexdatetime(date_labels = TRUE) + ggsave(“sankey.pdf”, width = 8, height = 6)
“`

In this example, we first load in the networkDynamics and ggplot2 packages, followed by creating a list of names and their associated variable counts. Then we use ggplot2::geombar to plot the data on the X-axis and color it by the Y-axis. Finally, we scale the color using ggplot2::scalecolor_manual to show the type of activity.

In this code, you can see that we have a dataset of variable counts and the names of the activities. We are using ggplot2::geombar to plot the data on the X-axis and color it by the Y-axis using ggplot2::geomtext to give each value a different color. This means that if you click on a particular text on the graph, you will see the amount of activity flowing in and out of that activity.

Applications of Sankey Charts

Sankey charts can be used in a variety of fields to visualize complex data. Here are some of the applications:

1. Finance: Sankey charts can be used to illustrate the flow of money in and out of different financial transactions, such as deposits, withdrawals, and loan repayments.

2. Engineering: Sankey charts can be used to show the flow of materials, personnel, and equipment in building and construction projects.

3. Marketing: Sankey charts can be used to show the flow of leads, sales, and customer service interactions, such as calls, inquiries, and customer feedback.

4. Science: Sankey charts can be used to show the flow of information, including research and development, publication, and citation.

Conclusion :

Sankey charts are an effective way to visualize complex data and they can be used in a variety of fields to demonstrate the flow of information, finance, projects, and activities. With the increasing use of datasets that require complex data visualization, Sankey charts are likely to become more popular in the coming years. By understanding the basics of how to create them, and their applications, you can gain a new tool for understanding and visualizing data.
