Describe what you want in plain English and the AI picks the right format — or choose one from the chips above.

Simple Line

A single trend line — the clearest way to show how one metric changes over time.

Multi-Line

Compare multiple series on the same axes. Ideal for year-over-year or segment comparisons.

Smooth / Curved

Bézier-smoothed curves for a polished look. Great for dashboards and presentations.

Step Line

Discrete jumps between values — perfect for pricing tiers, thresholds, or binary states.

Gradient Fill

Area tinted below the line to emphasise magnitude alongside trend direction.
