A D3.js plugin that dispatches scrolling events to synchronize explanatory text sections with interactive graph updates.
graph-scroll.js is a D3.js plugin that facilitates scrollytelling by linking scrolling actions to graph updates. It dispatches events as users scroll through explanatory text sections, enabling dynamic synchronization between narrative content and interactive data visualizations. This solves the challenge of creating seamless, scroll-driven storytelling experiences with D3 graphs.
Data visualization developers and frontend engineers building narrative-driven, interactive data stories using D3.js, particularly those creating scrollytelling articles or educational content.
Developers choose graph-scroll.js for its simplicity and tight integration with D3.js, offering a lightweight solution to manage scroll events without complex frameworks. Its declarative API and built-in CSS class handling reduce boilerplate code, making it easier to implement responsive, scroll-triggered visualizations.

Offers a declarative API that hooks directly into D3.js selections, making it easy to synchronize graph updates with scroll events without heavy dependencies.
Handles class changes like 'graph-scroll-active' and 'graph-scroll-graph' based on scroll position, reducing boilerplate code for styling active sections and graphs.
Designed to work seamlessly with `position: sticky` CSS, enabling graphs to remain fixed during text scroll for smooth narrative flow, as shown in the README examples.
Provides offset settings and media query examples in the README to adapt layouts for different screen sizes, ensuring basic mobile compatibility.
Tightly coupled with D3.js, so it cannot be used with other JavaScript charting libraries without significant rework, limiting its versatility.
Relies on a single demo page for documentation, lacking comprehensive guides, API references, or troubleshooting resources for advanced use cases.
Focused solely on dispatching scroll events for graph updates, missing features like smooth transitions, touch event handling, or built-in accessibility support.
