📁 File Structure

Each animation directory contains:

animation-name/
├── index.html       # Main HTML structure

🛠️ Development

Generation System

Seven animations (3-9) were generated using the automated system:

<h1 id="regenerate-all-animations">Regenerate all animations</h1>
python3 completeallanimations.py

<h1 id="enhance-css-for-generated-animations">Enhance CSS for generated animations</h1>
./complete_generation.sh

See ANIMATIONGENERATIONGUIDE.md for patterns and templates.

Customization

To customize an animation:

• Open animation.js in the animation directory
• Modify the setupSceneN() functions
• Add D3.js visualizations as needed
• Update narration text in HTML data-speech attributes
• Adjust timing in sceneDurations object

Adding Visualizations

Example D3.js visualization:

function setupScene3() {
    const svg = d3.select('#my-diagram');

    // Add circles
    svg.selectAll('circle')
        .data([1, 2, 3])
        .join('circle')
        .attr('cx', (d, i) => 100 + i * 150)
        .attr('cy', 200)
        .attr('r', 40)
        .attr('fill', '#3b82f6')
        .style('opacity', 0)
        .transition()
        .duration(800)
        .delay((d, i) => i * 200)
        .style('opacity', 1);
}
