# Synthetic Uniform, Hard

Uniform random matching synthetic benchmark with weaker connectivity.

## Benchmark Role

Stresses iterative methods more than the easy uniform case.

The v1 graph uses `id1` and `id2` as the two fixed-effect dimensions.

## Data

- Rows: 500,000
- Columns: `id1`, `id2`, `x1`, `x2`, `y`
- `id1` levels: 122,702
- `id2` levels: 122,655
- CSV SHA-256: `315b7115808b5d388edb92dd10f35595b602d40ef7723d791b4e5ee339d11e37`
