Creating a React Library for Consistent Data Visualization - Shopify

What this post added

This post details the creation of the Polaris Viz React library to address inconsistencies in data visualization across Shopify's admin interfaces. It introduces a `theme` prop for chart components to apply default light/dark themes and a `PolarisVizProvider` that allows consumers to define custom themes. Helper functions `createTheme` and `createThemes` are provided to ensure complete theme objects and maintain default themes. The library also allows individual data series to override theme colors.
