Building Composable Platform React Charts

Building web charts that are flexible, maintainable, and consistent is a challenge whenever visualization systems need to scale across products, teams, or entire platforms. Large-scale enterprise environments, with their diverse workflows, data requirements, and design standards, highlight the need for a robust approach. This talk will explore how to build composable React chart components that serve as the foundation of scalable visualization systems, enabling teams to deliver interactive, customizable, and performant charts while maintaining cohesion, reducing duplication, and embedding accessibility from the ground up.

React provides the perfect foundation for composable chart components. By leveraging its component architecture, props, and hooks, developers can create modular, reusable, and adaptable charts that are platform aware and easy to extend. Accessibility through keyboard navigation, screen reader support, and ARIA-compliant elements should be baked in from the start, ensuring all users can interact with and understand the data. This approach allows teams to balance flexibility, consistency, and inclusivity, turning charts from isolated components into a coherent, scalable system.

The talk will demonstrate how to put these principles into practice. It will cover patterns for composable components, API design conventions, and strategies for reuse, along with approaches for customization and overrides that allow product-specific adaptations without breaking platform-wide consistency. Accessibility will be highlighted as a first-class concern, showing how to design charts that work for everyone without costly retrofits. Finally, the session will address scalability, performance, and long-term maintainability, illustrating how a React-based charting system can evolve to support multiple products, large datasets, and complex interactions over time.

This topic matters because building visualizations at scale is as much about engineering a system as it is about displaying data. Composable, reusable charts let teams respond quickly to new requirements, reduce duplication, and maintain consistency across products or platforms. When accessibility is built in from the start, these charts work for everyone, helping teams minimize technical debt, collaborate effectively, and evolve their visualization layer alongside the products it supports.

The intended audience includes front-end and visualization engineers, UI/UX designers, and technical product leads who work on platform-level products or large-scale analytics systems. By the end of the session, attendees will understand why composable, accessible chart patterns are critical for scalable platforms, how to design charts that balance flexibility and consistency, and practical strategies for implementing a maintainable, extensible, and inclusive visualization system.
