Polaris Viz is Shopify's data visualization component library for React. It provides accessible, themeable chart components that match the Shopify Admin visual style.
Note: This library was archived in June 2025. While still functional, Shopify recommends reaching out to support for migration assistance if building new features.
Installation
npm install @shopify/polaris-viz
# Required peer dependencies
npm install @shopify/polaris @shopify/polaris-tokens
Setup
Wrap your application with PolarisVizProvider:
import { PolarisVizProvider } from '@shopify/polaris-viz';
import '@shopify/polaris-viz/build/esm/styles.css';
function App() {
return (
<PolarisVizProvider>
{/* Your app */}
</PolarisVizProvider>
);
}
Core Design Principles
- One Question Per Chart: Each visualization should answer a single, specific question
- Accuracy First: Faithfully represent the original dataset
- Accessibility: Support screen readers, color-blind users, and multiple data formats
- Consistency: Use Polaris themes for visual harmony with Shopify Admin
Available Chart Components
| Component | Use Case | Max Data Points |
|---|---|---|
BarChart | Comparing discrete categories | ~6 categories |
SimpleBarChart | Simple horizontal bars | ~6 categories |
LineChart | Trends over time | 30+ points |
SparkLineChart | Compact inline trends | Any |
DonutChart | Part-to-whole relationships | ~6 segments |
StackedAreaChart | Cumulative trends | 30+ points |
FunnelChart | Conversion funnels | ~6 stages |
Quick Examples
Bar Chart
import { BarChart } from '@shopify/polaris-viz';
const data = [
{
name: 'Sales',
data: [
{ key: 'Monday', value: 150 },
{ key: 'Tuesday', value: 200 },
{ key: 'Wednesday', value: 175 },
],
},
];
<BarChart data={data} />
Line Chart
import { LineChart } from '@shopify/polaris-viz';
const data = [
{
name: 'Orders',
data: [
{ key: 'Jan', value: 100 },
{ key: 'Feb', value: 150 },
{ key: 'Mar', value: 200 },
],
},
];
<LineChart data={data} />
Donut Chart
import { DonutChart } from '@shopify/polaris-viz';
const data = [
{ name: 'Direct', data: [{ key: 'Direct', value: 200 }] },
{ name: 'Social', data: [{ key: 'Social', value: 150 }] },
{ name: 'Email', data: [{ key: 'Email', value: 100 }] },
];
<DonutChart data={data} />
Spark Line (Inline Trend)
import { SparkLineChart } from '@shopify/polaris-viz';
const data = [
{
data: [
{ key: 0, value: 100 },
{ key: 1, value: 150 },
{ key: 2, value: 120 },
{ key: 3, value: 180 },
],
},
];
<SparkLineChart data={data} />
Data Structure
All charts use a consistent DataSeries format:
interface DataPoint {
key: string | number; // X-axis value or category
value: number | null; // Y-axis value (null for gaps)
}
interface DataSeries {
name: string; // Series label
data: DataPoint[]; // Array of data points
color?: string; // Optional color override
isComparison?: boolean; // Mark as comparison data (renders grey)
}
Theming
Use the theme prop to switch between themes:
// Use built-in themes
<BarChart data={data} theme="Light" />
<BarChart data={data} theme="Dark" />
// Or define custom themes in provider
<PolarisVizProvider
themes={{
MyBrand: {
chartContainer: { backgroundColor: '#f9f9f9' },
seriesColors: { upToEight: ['#5c6ac4', '#47c1bf'] },
},
}}
>
<BarChart data={data} theme="MyBrand" />
</PolarisVizProvider>
Color Guidelines
- Single series: Use one consistent color
- Comparison to past: Current = purple, Historical = grey
- Multiple series: Use contrasting colors (max 4 lines recommended)
- Positive/Negative: Green = positive, Red = negative
Accessibility Requirements
- Color contrast: Ensure sufficient contrast between elements
- Screen readers: Charts render with ARIA attributes
- Text alternatives: Provide data tables as alternative format
- No color-only meaning: Use patterns or labels alongside color
Common Props
Most chart components accept these props:
| Prop | Type | Description |
|---|---|---|
data | DataSeries[] | Chart data |
theme | string | Theme name |
isAnimated | boolean | Enable/disable animations |
showLegend | boolean | Show legend |
xAxisOptions | object | X-axis configuration |
yAxisOptions | object | Y-axis configuration |
emptyStateText | string | Text when no data |
Axis Label Formatting
Follow Shopify's formatting standards:
- Times: 12-hour lowercase (12am, 6pm)
- Days: Three letters (Sun, Mon)
- Months: Three letters (Feb, Mar)
- Dates: "10 Apr" format
- Numbers: Use "k" for thousands, max 3 digits + decimal + letter
Anti-Patterns to Avoid
- DO NOT exceed 6 categories in bar/donut charts - use tables instead
- DO NOT use more than 4 lines in a line chart
- DO NOT rely on color alone to convey meaning
- DO NOT use edge-to-edge axis lines - keep them within data range
- DO NOT mix Polaris Viz with other chart libraries in the same app
