Measured entry

ruixen-spark-chart

inputgradient-glowmotion on file

An interactive React sparkline that draws a smoothed SVG path, gradient fill, hover label, guide, and tracking dot. It ships as a client component from a shadcn registry and relies on React, Tailwind utility and theme classes, plus the project-local cn helper backed by clsx and tailwind-merge.

Verdict

A focused, polished sparkline for dashboards that need lightweight visual trends and pointer feedback. It builds and mounts in the prepared harness, but it needs a shadcn-style setup because the bare project cannot resolve its local utility import.

Use it if

  • You need a compact single-series trend view with pointer scrubbing.
  • You want callbacks for the interpolated value and active state.
  • Your app already uses Tailwind and shadcn-style aliases and theme tokens.

Skip it if

  • You need axes, legends, multiple series, or charting-library features.
  • Exact values must be discoverable by keyboard or assistive technology without extra work.
  • You need a dependency-free component that can be copied into an unconfigured React project.

In a non-shadcn project, add Tailwind with the expected theme tokens, configure the source alias, and provide a cn utility using clsx and tailwind-merge. Also define the spark draw keyframes if you want the entrance animation, or replace the project-specific classes and import with local equivalents.
