+# SPaRC Dataset
+
+A grid-based puzzle dataset for benchmarking LLMs spatial reasoning capabilities.
+
+## Data Schema
+
+Each record (JSON) includes:
+
+* `id` (string): unique puzzle identifier
+* `difficulty_level` (int) & `difficulty_score` (float)
+* `grid_size`: `{ "height": H, "width": W }`
+* `polyshapes`: JSON string mapping shape IDs to binary grids
+* `puzzle_array`: 2D array with cell codes (e.g., `S`, `E`, `+`, `P-O-112`)
+* `solution_count` (int) and `solutions` list (with `index`, `path`, `pathLength`)
+* `text_visualization`: YAML-style summary
+
+## Sample Entry
+
+```json

+  "id": "10e68dc3a6fbfcdf",

+  "polyshapes":"{\"112\":[[0,1,...]]}",
+  "puzzle_array":[
+    ["+","+","+","E"],
+    ["+","P-O-112","+","o-O"],
+    ["S","N","+","G"]
+  ],
+  "solution_count": 10,
+  "solutions": [ { "index":0, "pathLength":34, ... } ],
+  "text_visualization": "..."
