Does this skill support real-time data?

Yes, it provides implementation patterns for real-time updates via WebSockets or Server-Sent Events (SSE), including optimistic UI updates and smooth animations for new items.

Are the timeline components accessible for screen readers?

Yes, the skill includes specific WCAG/ARIA patterns such as semantic HTML roles (feed, article), aria-labels for timestamps, and full keyboard navigation support.

Can these components handle thousands of events?

The skill provides performance optimization strategies like virtual scrolling, memoization, and server-side pagination specifically for datasets exceeding 1,000 events.

What types of timelines can I create with this skill?

You can create vertical and horizontal timelines, social activity feeds, system audit logs, interactive Gantt charts, and various calendar views including month, week, and day formats.
