What it means
Sparklines keep a compact signal inside the row so users can read direction, shape, or distribution without leaving the table.
Visualization guide
Sparkline data grid documentation
Sparklines render compact trend visuals directly inside cells. This page keeps the dataset small and gives the chart-backed types more room so you can compare the full catalog without extra chrome.
When to use it
Use the showcase to compare the full catalog before you pick the shape that fits the story. Keep the dataset small and the row labels clear so the chart type, not the data volume, stays front and center.
Implementation notes
Treat sparklines as signal, not decoration. If the trend is not important enough to influence action, skip it. Leave the viewer off unless the larger surface adds real value, and keep the inline trend readable without it.
Relevant API
Start with sparkline.enabled, sparkline.defaultOptions. Open the live API reference for types and defaults.
