Quick Start

<Chart {data} x="date" y="value" tooltip={{ mode: 'bisect-x' }}>
	<Svg><Area class="fill-primary/20" /><Highlight points /></Svg>
	<Tooltip.Root>{#snippet children({ data })}{data.value}{/snippet}</Tooltip.Root>
</Chart>

Core Patterns

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