This program applies Benford's law to a set of numerical data and generates a graph.

Benford-Law-chart-generator

This project is a Java program that checks the distribution of the first digits of a set of data against Benford's Law. Benford's Law is an observation that in many naturally occurring datasets, the first digit of each number is more likely to be small (e.g. 1, 2, or 3) than large (e.g. 8 or 9). This law has been used to detect financial fraud and other irregularities.

The program takes an array of data as input, calculates the distribution of the first digits of the data, and generates a bar chart comparing this distribution to the expected distribution according to Benford's Law. The resulting chart is saved as a PNG image in the output folder.

Example

An example data array has been provided in the TestCase class. It contains the multiplication results of the numbers 1 to 10. When the Main class is run with this data, the resulting bar chart shows that the distribution of the first digits of the multiplication results closely follows Benford's Law.

Requirements

• Java Development Kit (JDK) version 8 or higher
• JFreeChart library version 1.0.19 or higher

Installation

1. Clone this repository to your local machine
2. Install the JDK if you haven't already done so
3. Download the JFreeChart library and add the JAR file to the classpath of your Java project
4. Compile the Main.java file in the src folder using javac
5. Run the compiled Main class using java Main

Usage

To use this program, you can modify the data array in the TestCase class to contain your own data. The data must be represented as an array of strings, with each string containing a single number.

Once you have set up the data, run the program by running the Main class. The resulting bar chart will be saved as a PNG image in the output folder.
