A clean, touch-friendly area line chart for tracking trends over time. The smooth line sits above a translucent area fill to emphasize magnitude, while the grid keeps values readable at a glance. Tap/hover to reveal a pinned tooltip with the exact value and a focus marker/vertical guideline (e.g., “40k” in September). Supports monthly/weekly/daily series, custom min–max, and responsive resizing without losing clarity. Colors, stroke width, and corner radii are fully themeable for light/dark UIs. Ideal for dashboards that need quick trend insight with precise point lookup.
