Default

Edit Example

A sparkline is a compact, word-sized chart with typographic scale, for data-dense layouts (text, tables, cards, dashboards).

Marks

Edit Example

Mark variants include line, area, gradient, column, and winloss to support trend and outcome signals.

Status

Edit Example

Communicates the intent and semantic meaning of an element to help users understand the outcome of their actions.

Status Description accent Highlights important actions or draws attention to primary interactive elements. warning Indicates cautionary actions that require careful consideration before proceeding. success Represents positive outcomes, confirmations, or constructive actions. danger Signals destructive or irreversible actions that need extra attention and confirmation. scheduled Task has a scheduled future execution at a specific time. queued Task is waiting in line to begin after other tasks complete. pending Task is awaiting approval, user input, or external conditions before proceeding. starting Task is initializing and preparing to begin active execution. running Task is actively executing and making progress. restarting Task restarts after an interruption or reset. stopping Task is gracefully shutting down and completing cleanup operations. finished Task has completed successfully with the expected outcome. failed Task encountered an error and did not complete as intended. unknown Task status remains unknown or unavailable. ignored Task was intentionally skipped or excluded from execution.

Inline With Text

This week's lane keeping safety score trend shows a steady rise after an early dip, with decreasing interventions per shift: , and predominantly successful route outcomes: .

Edit Example

Sparklines inherit font size and flow inline with surrounding text and metrics.

Data Grid

Autonomy Service Safety Score Interventions / Shift Route Outcome Lane Keeping Object Detection Path Planning
Edit Example

Embed sparklines in grid cells to add compact trend context to tabular data.

Explicit Size

Edit Example

Explicit size tokens set fixed sparkline height independent of text context.

Default Size

heading
body
label sm
Edit Example

Without a size attribute, height scales with the parent text size for typographic alignment.

Interpolation

Edit Example

Controls how the chart connects intermediate values between points in a data series. Defaults to linear.

Interpolation Description linear Connects points with straight line segments. smooth Connects points with smooth bezier curves. step Connects points with horizontal and vertical step segments.

Symbols

Edit Example

Symbols denote specific data points in line, area, and gradient marks.

Fixed Data Domain

Edit Example

Fixed min and max values define a shared vertical domain to ensure comparability across adjacent sparklines.

Zero Line

Edit Example

The chart renders a zero baseline when the data includes both positive and negative values.

Interval Length

Edit Example

Controls spacing between points in a line, in em (1 = chart height). Defaults to 0.6.

IntervalLength Description number

Custom Styling

theme
Edit Example

CSS custom properties are available to adjust dimensions and visual styling.
