Liquid Glass Analytics Widget

A dashboard KPI card whose frosted glass panel floats over a live SVG line chart, subtly warping the grid lines and area fill beneath it. High-contrast numbers stay razor-sharp on a solid tint while the chart behind is lensed by a real SVG displacement filter — the readability trade-off that Liquid Glass dashboards must nail.

## JavaScript
```js
/* No JavaScript — the refraction is a pure SVG feTurbulence + feDisplacementMap filter on the chart grid. Drop your own data into the path 'd' attributes and the glass lenses it automatically. */
```

How this works

The card is a backdrop-filter:blur(14px) saturate(180%) panel layered over an inline <svg> chart. A second SVG defines a feTurbulence+feDisplacementMap filter applied to the chart's grid group, bending the ruled lines so the glass reads as a curved lens. The KPI figure sits on a near-opaque inner chip so the number never drops below WCAG contrast.

Pure CSS/SVG, no JS. The card is a section with a heading, the trend is announced via aria-label, and the decorative chart carries aria-hidden.

Make it yours

  • Recolour the series with --series and the accent chip with --accent.
  • Dial refraction strength via the filter's scale attribute (0 = flat glass).
  • Swap the sparkline path d for your own data or generate it server-side.

Gotchas — read before shipping

  • feDisplacementMap is GPU-heavy on huge surfaces — keep the lensed layer small (here just the grid).
  • Firefox historically ignored SVG-filter backdrop refraction; the flat blur is the graceful fallback.
  • Never sit the KPI number directly on the blurred chart — always on the solid inner chip for contrast.

Floor set by oklch(), color-mix(), backdrop-filter as this demo is written. The core technique itself goes back further — Chrome 76+.

SVG displacement is progressive enhancement; the card degrades to a flat frosted KPI panel.
