LayerChart Svelte 5

Use next.layerchart.com docs (NOT layerchart.com - that's Svelte 4).

Quick Start

<Chart {data} x="date" y="value" tooltip={{ mode: 'bisect-x' }}>
	<Svg>
		<Axis placement="left" grid rule />
		<Area
			class="fill-primary/20"
			line={{ class: 'stroke-primary' }}
		/>
		<Highlight points lines />
	</Svg>
	<Tooltip.Root>
		{#snippet children({ data })}
			<Tooltip.Header>{data.date}</Tooltip.Header>
			<Tooltip.Item label="Value" value={data.value} />
		{/snippet}
	</Tooltip.Root>
</Chart>

Core Patterns

• Tooltip: {#snippet children({ data })} - NOT let:data
• Chart context: {#snippet children({ context })}
• Gradient: {#snippet children({ gradient })}
• Must enable: tooltip={{ mode: 'band' | 'bisect-x' | 'quadtree' }}

Tooltip Modes

| Mode | Use Case | | ------------ | ---------------------- | | band | Bar charts (scaleBand) | | bisect-x | Time-series area/line | | quadtree-x | Area (nearest x) | | quadtree | Scatter plots |

Type the Snippet

{#snippet children({ data }: { data: MyDataType })}
