title: Area Chart
description: Area charts for visualizing trends and cumulative values over time.

<ComponentPreview name="chart-demo" description="Area chart example" />
## Overview
Area charts are used to show trends over time or across categories. They combine line charts with filled areas beneath the line to emphasize volume.
## Usage
```tsx
import { ChartContainer, ChartTooltip, ChartTooltipContent } from "@hanzo/ui"
import { Area, AreaChart, CartesianGrid, XAxis } from "recharts"
const data = [
{ month: "Jan", desktop: 186, mobile: 80 },
{ month: "Feb", desktop: 305, mobile: 200 },
{ month: "Mar", desktop: 237, mobile: 120 },
]
const config = {
desktop: { label: "Desktop", color: "hsl(var(--chart-1))" },
mobile: { label: "Mobile", color: "hsl(var(--chart-2))" },
}
export function AreaChartDemo() {
return (
<ChartContainer config={config}>
<AreaChart data={data}>
<CartesianGrid vertical={false} />
<XAxis dataKey="month" />
<ChartTooltip content={<ChartTooltipContent />} />
<Area
dataKey="desktop"
fill="var(--color-desktop)"
stroke="var(--color-desktop)"
/>
<Area
dataKey="mobile"
fill="var(--color-mobile)"
stroke="var(--color-mobile)"
/>
</AreaChart>
</ChartContainer>
)
}
```
## Variants
### Stacked Area
Stack multiple areas to show cumulative totals.
### Gradient Fill
Apply gradient fills for visual depth.
### Step Area
Use `type="step"` for discrete step transitions.
