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.

AI-generated description

Assistive Technology Data Visualization

This project visualizes sample data for the availability of assistive technology across different countries and regions. The visualization includes a column chart showing AT Availability Index by country and a detailed data table.

Features

  • Interactive Column Chart: Displays AT Availability Index values for each country
  • Color-coded Regions: Different colors represent different WHO 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. In a real implementation, this would be sourced from:

  • Original assistive technology.csv file from WHO
  • External sources for literacy rate data
  • Calculated AT_Availability_Index from subcategory data

Sample Data Fields

Field Description
Country Nation name
Region WHO region classification
AT_Availability_Index Numeric score (1-10) representing assistive technology availability
Literacy_Rate Percentage of population that can read and write

Visualization

The main visualization is a column chart that shows:

  • X-axis: Countries (sorted by AT Availability Index)
  • Y-axis: AT Availability Index values
  • Color: WHO regions (Americas, Europe, Africa, etc.)
  • 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 records.
