This visualization presents sample data on VR technology's educational impact across 15 countries, showing VR Impact Scores as a sorted column chart with bars color-coded by geographic region and labeled with exact values. Hovering reveals tooltips with additional student engagement percentages. Built with D3.js, it uses `scaleBand`, `scaleLinear`, and `scaleOrdinal` alongside `axisBottom` and `axisLeft` to construct the chart. A complete data table accompanies the visualization. The code imports data directly from arrays, with all sample values stored in the `vrEducationData` object for demonstration purposes.

VR in Education Impact Data Visualization

This project visualizes sample data for the impact of Virtual Reality technology in education across different countries and regions. The visualization includes a column chart showing VR Impact Score by country and a detailed data table.

Features

Interactive Column Chart: Displays VR Impact Score values for each country
Color-coded Regions: Different colors represent different regions
Tooltips: Hover over bars to see detailed country information
Data Table: Complete tabular view of all data points
Responsive Design: Clean, accessible layout

Data Source

The data includes sample numerical values for demonstration purposes, representing the impact of VR technology in educational settings.

Sample Data Fields

Field	Description
Country	Nation name
Region	Geographic region classification
VR_Impact_Score	Numeric score (1-10) representing VR adoption and effectiveness
Student_Engagement	Percentage improvement in student engagement

Visualization

The main visualization is a column chart that shows:

X-axis: Countries (sorted by VR Impact Score)
Y-axis: VR Impact Score values
Color: Geographic regions
Bar labels: Exact numerical values
Interactive tooltips with complete country data

Technical Implementation

Built with D3.js for data visualization, featuring:

Scalable vector graphics (SVG)
Responsive design patterns
Accessibility considerations
Clean, modern styling

Note: The sample data is for demonstration purposes only and actual values would need to be sourced from official studies and research.

VR Game Data

This visualization displays the availability of assistive technology education programs across different regions, broken down by delivery mode: online, in-person, and hybrid. Using a stacked bar chart, each region shows the cumulative count of programs across these three categories. The chart is built with D3.js, employing `csv`, `scaleBand`, `scaleLinear`, `scaleOrdinal`, `stack`, and `axisBottom`/`axisLeft` APIs. Data is loaded from a local CSV file and rendered as SVG elements.

Availability of Education for Assistive Technology

This interactive visualization maps the global availability of assistive technology education programs by WHO region, with each country color-coded by region and filterable by training content type. It uses d3.geoPath with TopoJSON world atlas data to render the choropleth map and d3.scaleBand for the stacked bar chart comparing regional program counts across cognition, communication, hearing, mobility, self-care, and vision training. Hovering reveals country-level details, while the dropdown filter dynamically updates both map and chart. Data comes from a CSV of country-level survey responses.

Tech and Education

This visualization compares VR immersion, educational VR usage, and student engagement levels across six age groups, overlaying motion sickness trends as a line chart. It uses bar charts for the three primary metrics and a dashed path to show the correlation between immersion and engagement. The implementation relies on D3.js APIs such as `select`, `axisRight`, and `d3line` for rendering. Data is sourced from three Kaggle datasets covering virtual reality experiences, educational VR impact, and assistive technology training availability.

Engagement

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.

Impact of Virtual Reality on Education

This visualization compares learning outcomes between students using virtual reality and a control group across immersion levels. The line chart displays average learning gain by weekly VR hours, with spline-smoothed traces for each group and unified hover tooltips showing both metrics simultaneously. Built with Plotly.js and D3 for data processing, the interactive dashboard supports zooming, panning, and toggleable legend controls. The visualization draws from a Kaggle dataset of 50 students measuring VR's educational impact across demographics and subjects.

Education Scatter Plot

This scatter plot, rendered with D3.js (d3.v7) and SVG, visualizes program duration against cost for assistive-technology education offerings. Each circle represents a program, with color indicating accredited status via a scaleOrdinal color scheme. The visualization includes labeled axes, grid lines, and a legend. The code synthesizes the duration and cost data, as the original dataset from Kaggle lacks these fields. The plot is constructed using scaleLinear for the x and y axes, and axisBottom and axisLeft for the tick marks.

Virtual Reality Experiences

This interactive chart analyzes virtual reality user experiences, showing how average immersion levels and motion sickness ratings compare across VR headset models. Users can filter the dataset by headset type using interactive checkboxes, with bar heights updating dynamically. The visualization loads comma-separated data from a Kaggle dataset, then uses d3.group, d3.scaleBand, and d3.scaleLinear to aggregate and display average metrics per device in an SVG rendered with D3 v7.

The ratio of students in the country (Primary Education)

This visualization shows the ratio of students in primary education across countries, with bars sorted in descending order to highlight the highest ratios. A bar chart rendered with SVG uses D3 v7’s `scaleBand` and `scaleLinear` to position and size the rectangles, while `d3.axisBottom` and `d3.axisLeft` display the country-year labels and ratio scale. The data is loaded from a CSV file sourced from the Global Economy and tidytuesday dataset, with bars colored steelblue and axis labels added via SVG text elements.
