Vega Datasets: Official Reference Collection for Visualization Testing

Maintained by the Vega organization, this repository serves as the central collection of example data for Vega and Vega-Lite visualization projects. The collection was updated in March 2026 and provides the standard reference data used across the Vega ecosystem for testing and documentation.

Use Cases

• Testing geographic projections using included TopoJSON files
• Demonstrating time-series visualization techniques with stock and weather data files
• Benchmarking declarative visualization performance with multi-dimensional tabular samples

Strengths

• Official reference repository for the Vega and Vega-Lite ecosystems
• Updated as recently as March 2026
• Supports multiple formats including JSON, CSV, and TopoJSON

Limitations

• Heterogeneous schemas across files prevent unified processing
• Small sample sizes intended for browser-based rendering rather than deep analysis
• Individual file metadata and original source citations are not centrally indexed
