Live-Data Animated Hero for Analytics Products

What this builds

A full-viewport hero section where the primary visual is animated data: counting numbers, live-updating sparkline charts, streaming bar graphs, or particle-flow representations of data pipelines. The data animates on load to sell the "live" feel, then continues with periodic micro-updates to stay alive.

• Animated number counters that count up from 0 to target on viewport entry
• Inline sparkline SVG charts with animated path drawing
• Streaming data bars that shift and update on a cadence
• Realistic mock data generator with configurable volatility
• Intersection Observer-triggered entrance so animations fire when visible
• Static snapshot fallback for reduced-motion and print

When to use / when not to

• Use for analytics dashboards, monitoring tools, API platforms, fintech products, or any product whose value proposition is "see your data in real-time."
• Use when the hero needs to prove the product works without a demo video or screenshot.
• Do NOT use when the product is not data-oriented. A data viz hero on a design tool landing page is misleading.
• Do NOT use real user data in the hero. Use realistic mock data that looks plausible but is obviously synthetic.
• Do NOT use heavy charting libraries (Chart.js, Recharts, D3 full) in the hero. The hero should load fast. Use hand-drawn SVG or Canvas 2D. For full dashboard views, see the canvas-2d-performance primitive.
