Network Visualization in R

This repository is a course project that implements interactive network visualizations of character interactions. The data used is an Excel workbook containing two worksheets. It generates two network visualizations: a Force Directed Network and a Chord Diagram. These visualizations illustrate dialogue interactions between the primary characters.

Project Overview

This project aims to visually represent relationships between characters using two visualizations:

1. Force Directed Network – Displays character interactions in a network graph.
2. Chord Network – Illustrates interaction intensity between characters. Stronger relationships are shown with thicker chords.

Files

• main.R: The R script is used to generate the visualizations.
• interactions_data.xlsx: The input data file containing two sheets:
  • Primary Characters – List of characters.
  • Conversational Lines – Number of lines spoken between pairs of characters.
• index.html: The generated HTML file containing the visualizations.

How to Run

1. R: Have R installed.
2. R Libraries: Install the following libraries in R:

install.packages(c("readxl", "dplyr", "networkD3", "htmltools", "RColorBrewer"))

3. Generate Visualizations: Open main.R in RStudio or an R environment and run the script. It will first process the data in interactions_data.xlsx and then generate the HTML file index.html that contains the Force Directed Network and Chord Network visualizations.
4. View Output: Open index.html in a web browser to interact with the visualizations.

Live Demo

You can find a live demo here.

Visualizations

• Force-Directed Network displays character interactions as a network of nodes connected by links. Each node represents a character, while each link indicates the interaction frequency.

• Chord Diagram highlights interaction intensities. more frequent interactions have thicker chords between nodes.
