This interactive D3.js visualization explores Virtual Reality (VR) engagement in education through two linked views. An engagement scatter plot maps weekly VR usage hours against a 1-5 engagement scale, with color-coded points distinguishing the Impact and Education datasets, while solid versus hollow circles differentiate VR users from non-users. A secondary grouped bar chart displays user distribution across age groups and education levels, with dynamic filtering by education level. Built with d3.select, d3.scaleLinear, d3.scaleBand, and d3.csvParse, the tooltips provide detailed information on hover, and the UI supports toggling between datasets and views.

VR Education Data Visualization

A comprehensive D3.js visualization analyzing Virtual Reality adoption in education and user demographics, with interactive filtering and engagement analysis.

Overview

This project visualizes data from multiple sources to reveal correlations between VR engagement, usage hours, and user demographics. Features two main interactive views: Engagement analysis and User distribution.

Data Sources

The visualization uses data from:

  1. Virtual_Reality_in_Education_Impact.csv - Student VR usage and outcomes
  2. Modified_Virtual_Reality_in_Education_Dataset.csv - Educational VR implementation and user demographics
  3. Virtual Reality Experiences.csv - User VR headset experience metrics

Views

Engagement View

Interactive scatter plot correlating VR engagement levels with weekly usage hours across different datasets.

Features:

  • Toggle between Impact and Education datasets
  • Filter for VR users only
  • Interactive tooltips on hover
  • Color-coded by dataset
  • Legend with visual encoding explanation

Users View

Bar chart displaying user distribution by age group (5-year increments) and education level from the Educational VR Implementation dataset.

Features:

  • Grouped bars showing education level distribution across age groups
  • Education level filter buttons (All, High School, Undergraduate, Postgraduate)
  • Interactive bars with hover effects
  • Color-coded by education level
  • Legend identifying each education level category
